for now, autopia.org is an awesome site for car detailing fanatics.
edit: also want to hear tips on detailing the insides.
for me its as follows:
a) clean dash with nice microfibre cloth
b) use a fine brush (rabbit fur) to get into all the nooks and crannies
c) strip off all seat covers, and get in the seams to get rid of dust/sand/crap
d) pull all floor mats out and do a through vacuum
e) brush the seat rails, and apply some grease to the chair tracks/bolts
f) brush the door gaps and anywhere else i may have missed
