trans / oil leak...can anyone help?

I've got a moderate to minor leak of trans fluid and oil.

I'm trying to figure out exactly where the leaks are coming from so I can maybe try to fix it myself before having to take to a mechanic and spend an arm and a leg.

when I first bought the truck there was oil droplets on the oil pan and bell housing. The oil seemed to be coming mostly from the valve covers and the oil pressure switch. I bought some felpro perma-dry valve cover gaskets, but before I installed them I tried just tightening the valve cover bolts. They were VERY loose, so I just snugged them all up and changed the oil pressure switch and now it doesn't seem to be leaking from either of those areas the best I can tell.

I thought that I fixed everything, but today I noticed when I got underneath the truck it's still leaking, not as bad but still leaking.

I also noticed it's leaking trans fluid as well.

The trans fluid is all over the cross member area, and on the driver side on what I believe is where the speedo cable hooks up (I'm not sure if that is what this is LOL, maybe someone can confirm) and also on the gear shift linkage.

If it's not the valve covers or oil pressure switch leaking, what else can it be? Oil pan? Rear main seal? Anything else?

Also if it's leaking from the 2 areas I described on the trans, how do I fix that? What's actually leaking??

Here are some pics, any advice or help is greatly appreciated.
