My problem is getting the board straight on the jointer because they always seem to come out bowed, I know it has to do with pressure before and after the board enters the knives.

The way I do it is to feed initially with gentle pressure to keep flat to the infeed table. Once it's past the knives, slowly transfer the pressure to the outfeed, while maintaining some pressure on the infeed. You want to prevent concentrated pressure over the knives, as that will bear into the edge.
