Robbie,
Welcome! I also have a 2002 SX and recently installed PP. Assuming you have the black (graphite looking) dash know as Millennium edition, you will need the larger 5" dials. Also, be sure to tell them you have the V-drive because they need to send you the longer cord. I have the factory bimini, but I had to move my speakers above the tower to allow it to fold-up without hitting the speakers. As for parts, Capt Rick has made it easy to find the parts you need. Go to the TMS parts tab at the top right of the page and enter in a simple description in the search tab (like "cover"). Also, search the forums and you will find great discussions on biminis, radios, and PP. Under the Maintenance tab you will also find a lot of useful information including the owners manual! Again, welcome! Don't forget to post pictures.
