Could be your tires need balancing, or you need an alignment. The faster you go, the more it's going to wobble.
No. If there had previously not been any alignment issues, and as long as the new tires are properly balanced, you will not need an alignment.
Because your steering wheel is being turned, which puts your tires in another position rather than straight. You might need an alignment, or a wheel balancing.
Depends on when you had your last alignment and the condition of the tires you removed. It they were wearing perfectly even then you may not need an alignment. If you have not had an alignment in the last 36,000 miles you may very well need one. Judgment call on your part based on the evidence.
I'd at least have it checked, just to be sure everything's fine
