Though it applies to film photograhy too, as others noted, I also made the tripod mistake. I thought I hated using a tripod until I got my Gitzo along with a Really Right Stuff ballhead (

I'm pretty much a beginner myself, especially with printing, but...here are my thoughts on this after my experience with the 3800 for year... if you're just starting printing, I think it's easier to start learning digital printing on gloss and semi gloss papers. I started doing a lot on matt because I knew I didn't want glossy, and my prints looked like %^$^&^&. Now I do test prints on cheap glossy paper to get an idea of what I might have, and then work from there.
Finding the right paper for the look you want seems to be one of the most important things. For printing, I found reading Eric Chan's website and articles for the specific printer I'm using, (Epson 3800) was one of the most useful things I ever did.
Also for printing, print a ton and don't be afraid to waste paper at first.
And my latest, what I'd consider has been my biggest mistake....I take very many vertical shots and never printed them large. Until you print the standard 3:2 ratio large, the skinniness of the print might not be obvious to you. So now, I have a collection of fav. photos that can never be printed large. I'm attempting to crop 1/2" off the top of each, but it's hard to give up a 1/2" after you've grown attached.
