yes that is what you need. the gears are side-specific too, don't try to force them on the cams. the will only go on one side.
the one with the 'holes' in it goes on the passenger side, the one thats solid goes on the drivers side.
and yes you can re-use your factory cam bolts, they are technically torque-to-yield, but many people, everyone i know thats done cams, re-uses them, including myself. and no problems.
