As far as timing goes. Just make sure to line your camshaft pulleys up with the either the notch in the t belt cover on the drivers side or the seam of cylinder head on the passenger side for the cams (both should have the timing marks straight up). Then make sure your crank mark is also at pointing straight up (pistons in service position.)... Theres nothing else that is necessary for timing although make sure you line up the marks on your new timing belt with your cam/crank timing marks. Then I would personally rotate the engine over a few times with the plugs out and the tbelt tensioned to make sure everything works smoothly and you don't have any piston to valve contact/etc.
