Yes as long as you buy a name brand. Purolator, & Wix are excellent filters. Felpro is one of the best gasket manufactures. Avoid Fram filters. Toyota does not manufacture these parts. They are manufactured by a supplier such as the above.
The trans was built with RTV silicone as the gaskets.
Yes, always replace gaskets on any projects requiring them.
No, not really. Either ones will do the job if installed correctly.
Most if not all plugs have gaskets.

There are a few gaskets on a car:- Cylinder Head, Water Pump, Inlet Manifold, Exhaust Manifold, Sump Cover,Thermostat Housing,Transmission Sump,Tappet Cover,Valley cover,Side Cover,Sump Plug,Differential Sump Plug, Transmission Sump Plug, Oil Filter, Oil Pump,Fuel Pump, I'm sure there are more but these will get you started Also door gaskets and window gaskets.
NO you dont have to rebuild it, you have to replace the seals and gaskets. it also helps to know what type of vehicle this is for.
it's probably the head gaskets.
If a transmission is leaking fluid, it is likely that a seal or gasket has failed. Replace the gaskets and seals and the leaking should stop.
I helped a guy change mine (94 es300) and it took about 3 hours, but we were not professionals and had to make a trip to autozone.
If you do it yourself, the VC gaskets are $53.00 bucks at Autozone, and it will take you all day. If you take it to the stealership, they will charge you twice that in parts and about 3 hours of shop labor. So you will probably plop down something just shy of $500.00.
