If the alignment was good before you take the wheels off, it should be the same when you put the wheels back on. You MUST align the rear wheel in the swing arm. DO NOT use the marks on the swing arm. I use a tape measure to align the rear wheel. Measure the distance between the axle and the swing arm pivot bolt on both sides, the measurements should be the same.
Mounting larger tires will "slow down" the steering on your bike. That means it will take more effort to turn the bike.
I run Avon AM23/AM22 in 140 rear and 110 front, the thing steers like a bus. I find the stickiest tires are the Avon AM23 (race compound, not for the street, won't last very long) or the Bridgestone BT055 (again won't last long on the street).
