Without a laser type measuring rack, you can tape it, measuring for squareness and trueness. Forks can be a bit tricky. I've had little luck finding slight bends in forks while on the bike. Off the bike, roll it on a glass top table and watch for bounce, look down the lower fork tube looking for a kink or reflection. if there is any sticking during the compression/rebound = bent obviously. Hope this helps.

suspension, I prefer non-penske they require more maintenance, in general, then others do.
plastics, well good thing you can pick up track fairings complete from HB for very reasonable price, much less than getting stock stuff anyway.
