It depends on what you want to do. If you want to try to target a specific output file size then use two-passes. If that's not really a concern just do a single pass using -crf. See the wiki page:

Sure, if you are going to present the video via progressive download. Doesn't hurt if you include it either way. It just may add a few more seconds to the whole process.

"-pass 1" for the first pass, then "-pass 2" for the second pass.
