Why are escape pods used instead of transporters whenever an alarm sounds to abandon the ship?
If the antimatter containment is failing then power would be failing also.

Why would the Federation ban escape pods that come with manual override?

Why would any interstellar starship still bother with streamline body design?

How do my spacefarers not get crushed accelerating to 0.2c?
They won't be crushed. In fact, they will feel less than Earth gravity, so they will need exercise to preserve their bones and muscles' integrity.

How do I make a space battle both realistic, with physics in play such as no sound and weird motion, but also very epic and intense still?
Space battles, at least realistic ones will be done with computer targeting systems. Humans will not have a big task on the spaceship. I imagine repair and ensuring the AI/computer won't go rogue will ...

What is a good reason for every spaceship to carry a weapon on board?
For the same reason some do in real life. Ship (or landing pod) landing isn't perfect so when they arrive back on earth the astronauts need to defend themselves against hostile animals or scavengers.
