First off, VinceBot, thanks for opening this subsection of the forum - I'm very happy it's here!
Here are a few starting points for things that I've found informative or useful.
Matt Brooker, better known to most as D'Israeli has from time to time put tutorials, work in progress and some analysis of comic art and artists on his website and blog... I have included a few links to some pretty cool things that IMO, everyone wanting to get work should have at least scrolled through.
This very quick video
will tell you about getting started with colour in photoshop.
Searching his blog with the word process
for example, should prove most enlightening.
I'd advise a read through of his Low Life: Creation series too.part 1

, part 3

and finally, part 8
Where Mr. D'Israeli's website http://www.disraeli-demon.com/
is concerned - look at everything because it's cool - but there are some handy hints on colouring in the "education" section.
It's not just Matt who does this informative sort of thing either.Dave Taylor
, Kevin Nowlan
, Leigh Gallagher
and Dylan Teague
have all blogged about their process too.
For the painters out there look no further than Glenn Fabry's website:
and the step-by-step tutorial
There are many other artists that have reasonably regularly updated blogs. Sometimes you'll see a page of pencils go up, try inking a page of art that a professional has produced. You are guaranteed to learn something about their process.
A fantastic place to find a huge number of links to comic artists and other things of interest is Mark Kardwell's Bad Librarianship Blog
Hopefully that's got you started - go search, find things - it'll enrich your next round of samples.
