Generally, yes. If you have 8 Int and are, say, an orc, you'll get one fewer skill point per level, to a minimum of 1. (You multiply that result by four to get skill points for your first level, so it's always at least 4.)

How do my skill points get determined? Is it by level? (ie the level of rogue gets x number of skill points, the next level is barbarian and only gets y, etc)

Can someone explain why dungeoncrasher fighter is supposedly so great?
Because it's basically free. It's a nice little way to improve Fighter builds that costs almost nothing except more Fighter levels. The damage boosts are handy without being OP.
