Here-here on the tools: MOST phillips (cross head) drivers are relatively soft. It takes effort to find hardened tipped units. Sears Craftsman 'pro' line are. Xcellite makes them, as do Wiha (German, but web purchases are easy). I have found that the easiest way to get them is to go buy the 1/4' bit inserts for power driving at the hardware store (if you have room for them). The best of these are the Vermont American, as they have 'acr' (anti cam reduction) reduction ribs that run perpundicular to the flutes (little ribs that help keep the tool from sliding out as you turn the driver).
Another trick is to buy a hammer operated impact wrench (they are fairly cheap). By pushing down on them hard enough you force the spring to compress a bit. Do this while turning and it often is all you need. Just use the good bits (they come with a few hardened ones). it also seems to help because it gives you a large area to grip with.
Using the impact wrench (often with a hammer) and anti-seize, (the first time you take a screw out), you will save yourself a world of hurt. One caveat: using anti-seize changes the torque you should be using. I found a small refernce volume listing thes (and a million other things -- great reference, but can't remember the name) conversions. The product used may have this data available on its web site.
