It depends. The rule of thumb is for the second baseman to cover the base if a right-handed hitter is at the plate; shortstop for a left-handed hitter. The logic goes that hitters are more likely to 'pull' the pitch and having the infielder from the other side cover gives a team better defensive coverage.

A base runner can steal a base at any time while he is on base. The only reason they wouldn't give him the steal is if the ball was fouled or he was thrown out by the catcher.
if a batter swings and misses and a runner is on base and the runner is stealing then he can steal a base. Not sure what you mean though on a strike swing.
You never let anyone get an extra lead. Pay attention always. If you go to full motion they can take off earlier and maybe steal home.
