heh...wh40k games I can find with no problems. I am on pretty good terms with all the guys over there (should be considering how much cash I spend) I just never took the time to try it out. I talk to the gw rep all the time about painting techniques etc and the game itself, been invited to sit down and play, but havent just due to time. So many hobbies now, I would have to give something up. Maybe someday.
Now to you Neon, that figure is about two to three times the size of what you are working with currently. I would say goof around with em some and dont worry too much about what they are looking like off the bat. My blood angels have probably 3 or 4 different shades or red throughout the group, and that is from me screwing around with mixing different shades of red. I usually work in groups of 5 to 10 just to keep some uniformity, but not really concerned with it across the board. Work on the basics of getting a good even base coat first then move on to more advanced techniques (shading, highlighting, etc). you will soon want to apply a wash to the figures then highlight through drybrushing, at that scale your normal troops will look good. As you continue to gain confidence you can try other techniques such as layering, feathering, and blending. Some good references are the "eavy metal painting guide" and the "eavy metal warhammer 40,000 painting guide" from games workshop. Not sure they carry these under the same name but am sure GW still offers them in some form and if its like most of the book products from GW it will probably run you about 15 - 20 bucks each. They are acrylic centric and dont talk to artists oils at all. Other references I use are fsm's guide to painting military figures (my dads got it up stairs right now, may not be the exact title) and shep paines "How to paint military miniatures. Also, take a trip down to the gw or modeling club and talk to ppl about painting and if you get a chance watch them do it. Most folks like having someone interested in their techniques and are usually more than willing to share. Most of all, enjoy yourself, I do it mostly to relax and prove my eyesight is still just as good as when I was 18...hehe.
