For this you can build a suffix tree in O(n) and then convert it into a suffix array by performing a lexicographic DFS on the suffix tree.
See this for more.
Yes. At least one such algorithm is DC3. However I don't know if linear time construction is any faster than
for usual input sizes.
SA-IS algorithm has linear complexity, and is competitive with the
time algorithms. You can find a simple description here and the original paper with some implementation here.
