Oleg,
In response to your problems:
Problem #1: I can't attest to the actual dynamics here, but I would get a new mast base and install that fairly quickly. I think the dolphin striker bears a lot of the force of keeping it place as it loads up with pressure for the wind. I am not sure I would want to sail the boat with just corse screws holding that in place.
Good luck!
What drej said on #1. Get some new bits, but... Install them using stainless rivets. The screws will wallow out the existing holes and make a legit repair down the road impossible. Search youtube for blind rivets and hobie. Something will come up.
