is this all there really is to getting it back on and tensioned...
Reinstall the timing belt and set the belt tension. The timing belt should already be in it's loose state if you have followed the directions. Slip the belt back on, lining up the marks you made previously to keep the cam timing the same. After the belt is on the cam gear, put a mark on one of the cam gear teeth. Now go to the adjustment nut for the timing belt tension (14mm) and loosen it one full turn, then turn the crank counter-clockwise (wratchet, 19mm socket and 6" 1/2 inch extension) until that cam gear tooth mark you made moves the distance of 3 cam gear teeth. Finally, go back to that adjustment nut and snug it down good. This sets the tension on the timing belt.
