When I did mine I did have a few problems with bolts, mainly on the suspension. Ended up removing the wishbone and strut in one go because I could not split them.
I also had to chock the engine up on blocks because I only have one jack. The box comes out the bottom so you have to lift the car quite high.
It is also a mighty pain in the a*** getting the box back on, if you are doing it solo because the engine is free to wobble and you have to push it about a bit to re-engage the splines whilst negotiating the framework inside the engine bay.
I did it in a long weekend, but then I spent a day changing oil seals, gear oil, roll bar rubbers, generally cleaning and faffing about, if you crack on its a long days work at home, half a day in a garage with power tools I guess.
