Welcome!
1) People have had good results with the PIAA's and Sylvania bulb upgrades. The PIAA's are more expensive and only marginally brighter than the Sylvanias. I have the PIAA's on my 2001 and I think they are great. When they burn out - I'm gonna replace them with Sylvania's cause I'm not sure the PIAA's are worth the extra cost. (just my opinion)
2) Be careful with wider tires. If you get them too wide - then you may have rubbing issues when you are trying to turn. In the stock set up - the tolerances are kinda tight to begin with so there isn't alot of room to play with adding a wider stance. I achieved a wider stance by upgrading my tires from the stock Grabbers to BFG AT/KO's (31" 10.5)
