If your removing your flywheel already then its only 6 more screws to remove the timing plate and seperate it from the stator. Pro Design and Cascade make billet timing plates, which is great and all but its not a high stress part. Really I have no idea why you would want or need a billet timing plate. A better route is to get a Ricky Stator adj. timing plate. Its cast so its not as pretty or as strong, but you're never gonna break it and you can't see it once installed anyway. Its $35 for the RS plate, or $100 for one of the billet ones. All depends on if you like to waste money or not.
The keys work, but your stuck with a 3, 4, or 7 degree advance depending on the key. They're easy to install backwards thus retarding your timing if you don't pay attention. Also they've been known to shear causing major engine damage. I ran a 3 degree key from Alba for 2 years w/out a problem, but others haven't been as fortunate.
