well, you are going to have to learn latex to do anything good with it. i use texshop as my editor cuz it has some nice stuff built in. do a google for latex tutorials and you'll come back with all sorts of help.
fink installs everything in the /sw folder so it is all there. if you played followed the directions in the fink install you should have the appropriate PATH settings. if you have no idea what i'm talking about, say so and i or someone else can clear it up for you. hope this helps.
