operations with lists

I need help for three things:

1) are there any tips for operating with large lists/matrices (in the 
order of 512*512 or so)


2) is it possible to thread a compiled function over several lists.

3) is there any way to "intertwine" two lists?

i.e., if a and b are lists, is there a simple way to make a list that is 
{a[[1]], b[[1]],a[[2]],b[[2]],...}?

Thanks for any and all help.
