17 or 18 inch wheels, Pro's or Con's either way

although possible, from your line of questioning. I highly doubt you will push your car hard enough to warrant 3 piece wheels, or feel any negative results in handling going from 17 to 18' or vice versa, and if getting a decent wheel, the weight difference will not be noticable. Just get whatever floats your boat. If you have the money the 3 piece wheels look killer and usually are a higher quality, plus you get the option of buying new hoops if you want to change the backspacing. Basically IMO for you, just decide how much $ you want to spend, and which will fit/look better to YOU. There are plenty of tire choices in both sizes, and most aftermarket wheels will be plenty strong for whatever you want to do. Its possible that a 18" wheel will be heavier than a 17" but in reality if you are buyingi anything at all quality the differnece will be nill and hardly noticable.

My vote goes to a 18" wheel as you can package more brakes in them, you can get just as much tire profile, and they look better.

Oh, and don't stagger your wheels more than 1", no technical data other than it just couldn't be right just by looking at it, and plus it looks funny
