You've all helped sway my opinion and given me a better idea what makes sense for me. The irony of it is, I think I'm still going with Ohlins. Here me out though, I think this is actually gonna make sense, LOL!
For the front forks, you guys have convinced me that all I need is new springs, and a good rebuild. RaceTech was my first choice, and their rate calculator suggests 0.71 kg/mm spring rate (stock is 0.52 kg/mm). However, their site says that they don't actually have springs with that rate available. Cue sad trumpet sound. But guess who does have springs available that are exactly the right spring rate? Yep, you guessed it, Ohlins. I guess I could save a little money and go with Progressive, but they don't even list what the kg/mm is, so I feel like the Ohlins is a safer bet.
For the shocks, I would be thrilled if there was a way to have a set of ZRX shocks rebuilt to work with my bike. They are a direct bolt-on as far as the eyelets are concerned, but they are 1/2" longer than my stock Zephyr shocks. The bike feels plenty sporty for my skill level, and I don't want to raise the rear end up and make the front feel twitchier. So unless anybody knows if there is a way to shorten some ZRX shocks up a little bit (I already have a pair I could use), then I am on to plan B...
Obviously there are hundreds of shock choices out there, and to Nessism's point, I found a set of Bitubos for around $400 that would probably be great. However, I will confess to some vanity and desire to make my bike look cool, plus having a name I can trust on there. Once again, Ohlins. Yes, they're a little pricey. But surprisingly, they're more like in the middle of the price range, and also they're not adjustable to the nines. Preload only. I figure if they've already dialed in the compression and rebound at the factory (and I imagine Ohlins knows how to do that better than I do!) than it's less I have to worry about.
So other than figuring out if there is some way to make the ZRX shocks work, I think I have my plan. What do you guys think?

I would call racetech. I believe racetech can rebuild and revalve ZRX shocks. It's also possible they could limit the travel internally to make them a 1/2" shorter, assuming that leaves enough compression travel for your setup. This may not be much cheaper than those ohlins, but presumably the result would be custom trailered to your bike

.7 fork springs are very light. I'm very surprised the calculator would suggest that. How much do you weigh with all your gear on?
BTW, where to get the Gazi shocks for so cheap?
RaceTech’s calculator has you input your weight without gear, so that’s what I did. I’m about 170 lbs. in my gym clothes.
What’s “Gazi?”
I would call racetech.
I was thinking the same thing. I’ll do that before I do anything else at this point.

Sorry, I was thinking Biturbo was a Gazi shock model. Nevermind on that.
I put .9 springs in my 750 and they are far from "stiff." I'm about 20 lbs heavier than you, but that won't make a difference. .7 springs are way too light unless you plan to use for air pressure.
BTW, YSS makes some nice shocks. You can get some with adjustable damping for a good deal less than those Ohlins you are looking at.

I would pick something with adjustable damping. It comes in handy now and then.
If I end up getting the ZRX shocks to work, I’ll have preload, compression, and rebound adjustability. Hoping that’s less than the cost of the Öhlins, but we will wait and see. I called RaceTech this morning, they are gonna look into it and get back to me.

They are almost 2 inches longer than the Koni shocks I had on before.
I had the front end lowered for years, forks slid up in the triple clamps, so moved them back to stock height.
Also have an 18" front wheel, so that must lower the axle 1/2".
First few rides I could feel a little difference; the bike sits higher and corning was different, but now after many rides she feels normal.
My ZRX got Ohlins rear shocks.
Noticable improvement in ride over the stock shocks.
The front end needed some help, and adjusting them with the help of Steve who sold me the Ohlins helped.
Both the KZ and ZRX will get some front end attention this Winter, RaceTech Emulators and rebuilds are in the plan.

On the front end, there’s still the option of the Öhlins replacement springs (and rebuild). I have not yet gotten any info from RaceTech if they can supply springs or not, but I will ask them if I decide to go with them for the ZRX shock rebuild.
So on to the quote for the shocks. For a rebuild and lowering of the ZRX shocks, they quoted about $720. I can pony up extra to have gold valves installed, which would run about $1330, but that’s pretty much out of my budget and probably more than I need. But $720 is less than the Öhlins I was looking at are currently selling for, and I’d have 3-way adjustable KYB shocks that would look I think much more like they belong there instead of being aftermarket. Of course, they’d still have to shipped, I don’t know what the lead time is for the service, and I already dropped $270 to purchase these ZRX shocks in the first place. So ultimately a lot more spent.
What do you guys think? Worth it?
