lots of questions!

Well, to start with, the low beams are 9006 and highs are 9005, you are correct... the Silverstars are AWESOME! However, they do not make a H3 bulb at this time, and yes an H3 is what the stock fogs use.

The 90-91 tail lights are the same design as the wagon lights (turn signal on top, brake/tail on bottom) but I am not 100% sure if they fit. They look the same. Park next to a 90-91 accord and check 'em out... or if you know someone with one, try swapping the lights to see if they fit properly. I agree that the red/clear lenses are very nice, and would look the best on a white car!

You'd be pleased with 17's, especially if you live in an urban area, or your area has a lot of bad roads. If you get 17's, go with the 215/45-17 tires... as a 205/40-17 is usually used on a civic/integra and would be too small of a tire for an accord (very low-profile!)

If you were to get 18's, the tire with a smaller sidewall would be best... so probably the 215/35/18... but mind you that is a very low profile tire, and you can easily bend your wheels on potholes... etc.

There are pics of my 94 sedan in my signature... I have 17's with 215/45-17 tires, so that may give you an idea of what they'd look like.

There are cat-backs made for the wagon... ive seen them before, you just have to search carefully for them, as I know the choice of manufactures is rather limited.

keep us posted... I love tricked out wagons!
