Digital BW, The Print

Just bought an HP DesignJet 3500CP - Need Resources & Info

I'm an old print-maker and postermaker, and muralist who's FINALLY 
just upgraded myself from my 500 year old "media-evil" printmaking 
techniques to the 21st Century by buying an HP3500CP.

I need some resouces...

Can anybody suggest some Forums, NewsGroups, and Mailing Lists that 
discuss using DesignJets for art printing.

I need to locate all those little technical "gotcha's" that make it 
all so worthwhile...

I'm looking for good quality UV bulk Inks for my HP DJ.

I'm looking for good roll Media, Canvas & Paper to Print on.

I'm looking for those pesky little ICM and ICC profile files that 
everyone is talking about.

I'm looking for software to write or program those pesky little ICM 
and ICC files.

Can you help?

Thanks.
