I think crackstore is (was) one of the best sites for noobs. they offer(ed) many tutorials. seems that crackstore is dead, there are no more updates, but I have good news, too
there are still some tutorials which can be downloaded, but you wont find them at the "tutorials" link. if you click the link "gamecracking" you'll get a short info about jumps and API functions and the following tutorials are still downloadable (except the ones which are marked as new)
