1. You'll need vise-grips more than likely to get them out, but first, take the screwdriver, put it against the screws, and give it a few sharp whacks with the hammer, then take the vise-grips to the screws. You should have done that first.
2. Go to Sears and get a tool called an impact screwdriver for next time.
You should have asked before you screwed stuff up. Rook.
Every project is an excuse to buy tools. You clearly don't have enough.
