JAny one tackle a rebuild by themselves or would I be better off handing it to a pro
Buy the ATRA manual and look through it. Ron Sessions' T350 rebuild book has some useful workaround for improvising clutch pack compressors, etc. that might prove useful even though it's for a different transmission. Besides compressors, you'll need feeler gauges, a dial indicator and stand to check end play, a rubber-tipped air nozzle to check clutch pack operation, a compressor or air tank, a slide hammer and piece of angle iron to remove the front pump, and a bushing driver kit. Plus some dental picks and odds and ends...
Figure up the tools you'll need. You need a clean place to work; I use a hollow core door across sawhorses and cover it with newspaper. Take LOTS of photos. Bag each subassembly in plastic grocery bags and sandwich bags. Clean the case first, then clean and rebuild each subassembly and install them.
If you're changing all the bushings, select-fitting steels and frictions (thickness varies according to manufacturer), shimming proper end play, etc., it can take a while. But it's not rocket surgery, and once you have the tools and a build under your belt, the next time is almost a no-brainer.
Here's a page I made about building a T350:
