If you go tothe Video Training section of this site there is subcategory for texturing tutorials... If money is scarce (trust me I can relate) then the least expensive would be the cyclops tut as it only has 4 parts. The others, the apache, the mech, and the frog are all over 9 parts and range from 20 to 27 points.
If you can afford Mike McKinley's book on Maya for Gamer Artists, there is a good section in it on UV editing.
Good luck on this venture.
