Not really sure where to start, need help..

Alright, that's a ton of info but here is wher I am at right now.

I sprayed penetrating oil down the sparkplug holes around 4 times, I haven't tried to crank going CW, since it looked like it loosened a belt? It spins CCW with ease now. I removed all the oil from the pan, but when I went to put on a new filter I couldn't remove the old one. I bought a oil filter wrench and some Marvels. Will be doing the rest of oil filter and pouring onto the valves. I need to check Autozone for a gasket, advanced auto was out.

So that's where I am at right now. Is there a tutorial on setting the valve lash?
