More often than not, the cases are optimally solved by going through the phases, and after you do a couple hundred solves, almost all of the orientation cases will become automatic. If there are any you are having trouble with, let us know.
Check the Roux thread though. At one point, someone posted the alg for every EO case, I believe.
is it a V-2b? breaking it in or just sanding down some imperfections should help tremendously. the V-2a seems to be higher quality out of the box, too.
Are there any good tutorials for 7x7 last two centers and last four edges? Right now I'm intuitively permuting as many center cubies I can and then using the commutator in lancetheblueknight's tutorial. For the last four edges I do the inner edges first and solve parity if I have it then I do the outer edges and apply parity if I have to.
Edit: Also, any mods to improve anything would be welcome. The only one that I know about is the adjustable core mod.

I don't know about optimal for all of them but I do agree for the most part.
You basically need to get good at the M' U(') M' trigger... then for some cases you can cancel some moves instead of M' U M' M2 you can do a M' U M
Also you can look ahead to the Opposite layers and manipulate the Edges.
