new member - some questions

[NYSUT]

hey all,
been reading for awhile - finally signed in
2006 h2 sut all black (in progress?)
quick questions (you guys seem to have been through it all atleast once)
1. someone gave me aftermarket tail light guards (black ofcourse), i think i like the GM factory ones better- any opinions/experience?
2. ordering black grille - tough to install?
3. have seen stock rims powdercoated black (prob. what i am gonna do) - what about the plastic "chrome" center cap (spraypaint?)?
4. been working out bugs from an ipod install (stock radio w/ 1 cd and xm), and an xm to sirius switch kit - any exp.?

thanks in advance,

bill
