Nice SE you got there, same color as mine. I went with this kit for the HIDs.
Xtreme Digital HID Conversion Kits With Philips Bulbs
I like that style kit because instead of running off the factory harness for power, it has separate relays that run off the battery to supply power to the kit.
I would just get the color matched grille if you don't like the chrome. My 99 had the chrome grille, mirrors, door handles and rear bumper when I got it and I hated it so I had them all painted to match.
Good plan to get the maintenance done before modding.
