Sorry to hear of the rearending... you can try www.hondaautomotiveparts.com for the harness/lights... whatever is missing.

The odometer light and clock light are 2 seperate bulbs... it could be possible the bulbs are just bad... you'll have to pull them out and check the bulbs to see. Also, make sure there aren't any bad fuses... knowing Honda, theres probably a seperate fuse for those 2 bulbs somewhere.

As far as the headlights go, thats a really good question... Installing "white" type bulbs makes the beam pattern more apparent, so you'll notice the flaws more. If you have any buddies with the same car, check their beam pattern... see if the left side is suposed to be more like the right side. I know in my 5th gen accord, the left and right beams were very similar. Start by checking to be sure the bulb is seated properly in the housing. If worst comes to worse... you may have to replace the headlight with a used one off ebay or something.
