READ THIS- I've recently made a video including things I left out of my 5x5 tutorials. I would imagine it could help you a lot. here it is- http://www.youtube.com/watch?v=M1ar6vl2rBg
If you can understand these algorithms, you will be able to finish solving the 5x5 rubik's cube.
Parity 1-
2R*, 2B, 2U, L*, 2U, R'*, 2U, R*, 2U, 2F, R*, 2F, L'*, 2B, 2R*.
Parity 2-
L'*, 2U, L'*, 2U, 2F, L'*, 2F, R*, 2U, R'*, 2U, 2L*
I got the algorithm for parity 2 from http://www.bigcubes.com/5x5x5/lastedges.html
