redbread,
thanks for the input. the new pedals are a lot thicker, and the new skate style shoes also have a much thicker sole (so i raised the seatpost by about 5mm to compensate for the added distance between seat and spindle centerline).
i'll try some pedal extenders (to increase the q-factor), then i'm going to schedule a fit session at a local bike shop, and take the old pedals/shoes with me. the specialized BG fit session, tho pricey, seems fairly comprehensive. fingers crossed

I'd venture to guess that your change in pedals and cleats probably moved the cleat away from the ball of your foot, and that combined with less float works against you. If the soles of your new shoes are a different thickness than the old ones, and if the spindle height on the new pedals is different, it's possible that you're overextending your knee.
A proper fit is priceless, road or mountain, and a good fitter will be able to adjust things for your needs. It's best to take as much of your own stuff as possible; saddle, shoes, pedals, riding shorts, gloves, and if possible, bar and grips.
The distance from the top of your saddle to the spindle of the pedal should be the same for all riding, on all bikes. Some folks will lower the saddle position a centimeter or a little more for a cyclocross or downhill bike, but big adjustments from the ideal position are generally bad. The horizontal relationship between the saddle and the bottom bracket should also be constant for each bike, and specific to your fit.
Knee pain is bad, and should be addressed before it gets worse. A good fit should address this issue and provide a good dose of happiness.
