Red targa I presume you jack the cross members off the garage floor then insert jack stands between hoist running boards and car sills?

What are the mods you made to your trolley Jack and Jack stands?

Better measure my garage again, a hoist would be so handy.

You could do it that way but it is easier than that. 
When I first got my hoist I realised that using it would require strict discipline at all times, so I took things very carefully at first until I got used to a safe routine, something everyone should think about.
 
My routine to get the rear wheels free first move the car near to the opposite end of the runway and chock the front wheels, then:
1. Raise the car on the hoist about one meter off the floor.
2. Fully raise the trolley jack and position it under the X member. (easy because there is no weight on it yet)
3. Slowly lower the hoist while locating the trolley jack under the X member until the weight of the car is on the trolley jack and until the wheels are free, then you can position the jack stands.
4. Raise the hoist up to a convenient working height.
 The front is done the same way.
 
 
The mods to the jack stands (you only need 2) were to modify the tops with hardwood inserts that really grip under the side jack points.
I also mounted them on a 19 mm MDF base to spread the load on the runway, with has non slip rubber stuck underneath the MDF base. 
 
The trolley jack tops I made fit in place of the stock cup, and locate around the center of the X member on the rear. The one for the front spans the circular molded ring in the plastic under tray. Although it takes the weight of the car through the plastic it doesn't damage it, but it must be precisely located under the front X member.
If you want I could take more pics.
 
Edit, I found another pic. 
 
 

Thanks for the info. Is it too dicey to use jack stands at both ends?

Cheers

I have done that and I even modded 4 jackstands for it, and the car was stable, but I rarely do it because with most stuff like suspension, brakes etc you mostly only need to work on one end at at time.
 
Safety wise you could consider it much the same as working on the floor, where it is obviously safer with one pair of wheels grounded and chocked.
 
Of course this procedure will only work with cars like the MR2 that has a front and rear X member that can be used as a jacking point as well as the 4 side jackstand points.
I also have a Falcon ute that I have had on my hoist to do stuff like oil changes, but I can't get the wheels free on that.
