Absolutely do NOT hang bolts from T-nuts. You're asking for some SERIOUS trouble in doing so. Anyone takes a good fall it will rip the t-nut and a bit of the ply wood clear out.
All of the information on building walls found on the internet is for homebased gyms where ropes/anchors/bolts will never be used.
I can't really explain how commercial gyms without photos, and unfortunatly photos cannot be found right now.

Yeah never hang bolts from TNuts it will always tear it out and is very dangerous. Drill the bolt directly into the wall.

I take it you want a wall thats bolted for leading? If so, all bolts should NOT go through t-nuts.
This said, always ancor through the existing framing, whether it be metal of wooden.
Anchors through t-nuts will only rip out when a fall it taken on them, so don't even think about using t-nuts as golt anchors.

Like piano said, hard to 'splain without photos, and I'm largely guessing here, but I think this would work out well...
Your wall should have vertical studs spaced ever few feet apart. The bolt should be placed somewhere in between these studs, not too close to them. In the space behind the wall you want to add a layer or two of plywood to thicken the wall. Maybe two square pieces about 1-2' square. Next you want to take a piece of 2"x4" and place it horizontally across the studs behind the place where your bolt will be placed. Now drill a hole through all of these pieces of wood, grab youself a super long bolt, slide it through the hanger, through the wall and your plywood backup, and through the 2"x4". Now toss a couple of washers on, and screw that badboy down.
The gym I climb at uses metal plates as reinforcements as well, but I'm not sure how feasible that is for a personal wall.
Like I said, that's just theory from looking at what most gyms use.

As long as your using thick plywood 3/4 in. You can use metal plates to reinforce the plywood. The only thing you need to remember is to have the metal plates wide enought to reinforce the wall and not get in the way of the other t-nuts.
So it would go like this:
Long bolt with a hanger and a couple of washer. Thread that through the wall to the metal plate (6in by 6in)couple of washers and lock nuts on the back. Make sure that the nut is on good. I use two nuts to stop the nut from coming loose. The key to this "system" is to have the bolts close so they share the load.
Now for the anchors at the top of the wall. I would use a 2x6 instead of the metal plates. Just to be safe, back them up to a stud with some webbing.
Hope this helps

In case you don't know any better, the previous post was either sarcasm (I hope) or just plain wrong and unsafe.

If you are looking for something easier, try a lag bolt into your wood stud.
To do this drill a pilot hole, 1/8" smaller than the lag bolt you are going to use(should be a 3/8" bolt 3" long). Put on a hanger and screw it down.
If the studs of your wall are very dry, drill the hole a little bigger. Remember, if you want the bolt to hold there must be a good deal of resistance when you put it in.
Another trick, put soap on the threads to reduce friction as you tighten the bolt.
good luck
