how about differential oil and thermostat (since you're working on the timing belt).

crank and cam seals to prevent leaks
bushings for comfort
control arms still ok?

The differential is integral of the transmission and takes the same T4 fluid. Definately do your cam and crank seals if you're going to have the t-belt apart. Might as well do the idlers for the timing belt as well. You dont have spark plug wires, so nothing to replace there. Might want to consider flushing the brake fluid though. Otherwise, it sounds like you got everything.
