OLL for 2x2 are just your 7 OCLLs....there are 5 PBLs...5 PBLs that are extremely easy, two of them are PLLs you probably already know (or should know if you know 2LPLL), and the other 3 are incredibly easy to memorize.
Double J Perm (J on top and bottom): R2 U' R2 U2 y R2 U' R2 - think of this as two R2 U' R2 (one nice finger trick) sequences separated by a U2 y
Double Y Perm: R2 F2 R2 - this shouldn't need much explanation
J on Top, Y on Bottom: R U' R F2 R' U R' - think of this as a sequence, then an F2, then the inverse of that sequence. This is also a nice finger trick.
