Yes Mark, Buy the Dave Wellings book as above, It's a good authoritative book. You are in the right place on this site for help and advice so use that. For some reason the TM search engine is.... well next to useless but a google search will more than likely pull up threads from here. You will soon get to know current dealers and after market experts who are only too willing to help out as well. Best of luck with the new 4/4 and hope you enjoy th new car.... a lot!
