What I've noticed in these cars is that they don't trap air easily. No special bleeding required. Just fill the reservoir as much as you can then start it with the heat on full-temp. Eventually the level will drop and you just keep refilling it until it dosen't do it anymore. Then cap it. You may have to top it off over the next couple of days.

The radiator itself is a piece of cake to replace. It's totally 100% straightforward. In fact the only annoying bit was unplugging the fan from the relay and un-doing it's ground cable with the battery it the way.

And as far as the trans fluid. You wont lose enough to make an appreciable difference in trans fluid level (unless you're low to being with). After replacing my radiator I didn't have to add any.
