You have a pretty good list of mods. Another tank to consider is the Clarke 3.6. This is what I'm running and so far I'm happy. A little wider than stock but holds the most fuel and was cheaper than IMS
Also uses the stock shrouds. Here are a few pics to show you what it looks like on the bike.
Stock gearing on the '07 is 13/50. I don't think your gearing will need to be changed to 16/40 as you mentioned. Not even sure if a 16t will fit? For minimal road riding the WR will be OK, but for any extended time there are better choices such as your 650L. Might take Maniac's advice and try a 15t first and if you still need more drop a few teeth in the rear. Once you get to the dirt you will like WR, but long stretches of pavement are not its strong points.
The HID is a nice addition if you plan to do a lot of night riding. You can save a few bucks by "floating" the ground on your stock stator by following these instructions http://www.bajadesig...-stator-mod.pdf
, or for $30.00 you can send it to Baja Designs
and let them do it for you. Turn around time was fast and they are very knowledgable. You will need to purchase a regulator/rectifier also, then you bike will be putting out about 100 watts. I am running the Airtime HID http://airtime-hid.com/
on my '07 with just the ground float and have been able to run low & high beams together and have not run into any problems.
The WR is a great bike. Its reliable, comfortable and easy to maintain. Parts are easy to find and not too expensive either. As long as you are dual sporting it with intentions of "connecting" trails and not long distance road rides you will be happy. Just find a clean bike that has been well cared for and you will have yourself a great bike.
