You can get the bolts for the tranny at the dealer. It really isn't an item that they overcharge for.
For the oil leaks, the most common leak in the front is the oil pump seal. All you do is remove the harmonic balancer and it is staring right at you. Remove and replace. The seal is very cheap.
About 10 years ago I noticed that I was getting a little seepage of oil out of my oil pan. I found out that the bolts were so loose that I could snug them up by with my fingers so you may want to properly torque those down. Rear seal gets pretty involved. The seal itself is easy to change but removing the tranny and transfer case is where the real fun begins. If you decide to go this route, replace the clutch and all of its components and have the flywheel machined.
