Set a per-question pace by dividing the section time by the number of questions, answer the easy questions first, and abandon anything you have read twice and are still stuck on. A hard question is worth the same as an easy one.

The question first. Reading the question and options before the passage turns reading into hunting for one specific thing, which cuts the usual three passes over a passage down to about one and a half.

Skimming is reading fast for the gist — topic, structure, tone — and you use it on the first pass. Scanning is hunting for one specific item such as a name, number or keyword, and you use it once you know what the question asks.

No, so never leave a blank. An unanswered question is a guaranteed zero you chose; a guess costs nothing.
