OLL = orientate last layer (make the top colour of all the top
layer cubies the same) and PLL = permutate last layer (put the last
layer cubies into the correct positions)
for a quicker method, try fridrich CFOP system. basically, its
cross (same as beginner method), then corner-edge pairing x4
(fridrich f2l), then OLL, then PLL. 57 OLLs and 21 PLLs for you to
learn, nothing to understand really.. just need to memorize them.
for F2L i suggest you going to youtube and searching 'fridrich f2l
tutorial'
