Replacing clutch and manual transmission -- what else?

I've got a rebuilt transmission and a new clutch/flywheel that I'm going to have installed. Is there anything else that I should replace while everything is taken apart? I'm particularly interested in any gaskets or seals that might be easily replaceable so that I can avoid oil leaks down the road. Are there any seals/gaskets between the transfer case and transmission? It's a 2000 4x4 SR5 V6 TRD. R150F transmission.

 

rear main seal, motor mounts, tranny mounts, u-joints, carrier bearing, x-fer case input/output shaft seals. really isn't anything else except the shift ball bushings. rebuilt tranny should come prefilled or at least with new crush washers.

 

Thanks!

 

Yip id definitely do the rear main also as codeseven mentioned!
