I have done both the TB service and a clutch replacement/tranny rebuild.
The ONLY thing that I can see that would be better with the whole engine tranny package out is doing the valve adjustment on the rear head, and it only took me 45 min to do the complete valve adjustment. Now that is with the valve covers already off for doing the timing belt service. The hoses can easily be changed with each of the individual services. The thing is, with the engine in the car you can easily get to the top and bottom. You are going to be dealing with quite a bit of weight with the whole package too.
I do all of my work in my garage with a floor jack and four tall jack stands ......by myself. I use a big piece of carpet pad with flat cardboard on top of it to lay on. Really pretty comfortable.
Good Luck, be careful and have fun,
Brad
