Here is the page of the repair manual which specifies the jacking points:
 

I very much dislike those jacking points because I think the car will crush the 4 points on the edge, and the two in the middle are not convenient for me.

^ Ow come on man, if those points are inconvenient for you - you don't know jack!...

Let me introduce Trolley Jack, and his offsider, Jack Stand.

 
Cheapish, and perfect for centre jacking.

Oh I have a trolley jack, and the stands, I would just think my jack stands would be crushing the point that one is sitting in there and I don't particularly want to bend them.

That pic isn't an MR2, its just a random jack and stand pic. Surely there's places where the stands could sit. I know what you mean, I hate the idea of that section getting crumpled. I'd say put the stands along the cross member and use wheel stops so the car doesn't move and roll off them.

I'm thinking about just cutting some metal blocks up to make standable points.

^ as long as they don't tip off and you get a case of SW head.

I'll make some good blocks that hold onto the stand :P not just ones that sit there.

All installed and tighter than ever. Some effort involved but I can now safely park on hills once again. Feels nice.
