I have A perms, N perms, Y perm, V perm, E perm, R perms, F perm, and G perms. For OLL I need to learn pretty much all of them.
Edit: I plan on learning PLL first because I am about 3 second with 2 look OLL but about 7 second with 2 look PLL. I plan on starting with a perms and working my way down. I know J, T, U, H, and Z perms
I would recommend learning them in this order: Y F A R V E G N; you could switch them around slightly, but I think this general order is best. I use the algs on that sheet for everything except the R perms and the G perms. For Ra, I use the 3rd alg on the pdf, Rb I use R2 F R U R U' R' F' R U2 R' U2 R.
