Beginner Intrested in purchasing a Disco I--Help Please.

[cxavierc21]

I am currently 15 and, sadly, have a few more months untill I can drive. For as long I can remember I have been fasinated by off-road vehicles, Land Rovers in peticular. For the past two years I have been working to be able to afford a Discovery. I am planing on spending $3500-$5000 on the vehical its self, the cheaper the better(more money for after-market upgrades.) I would like information/advice on everything from selecting a vehicle to the order of upgrades. Here is a list of thing I would like to do(feel free to change it):



1.) Paint Job. Would be a good idea to do first?
2.) ARB Bull bumper. If I opt not to get the winch at first can I later?
3.) FULL roof rack w/ Jerri cans. Can someone recomend a specfic rack? Also is there a cheaper way to attach the cans to the rack than the $79.99 attachers?(Don't know what they are called)
4.) 2" lift. I liked the PRO COMP ones (because of the yellow springs, not any profesional reason haha) in this months Rovers North mail-issue, are those any good?
5.) A set of bad-ass looking off-roading tires. Being 15 makes asthetics paramount.
6.) Window Tint.
8.) Any Internal/Engine/Preformance Enhancing Upgrades. I don't know much about this.
9.) A differential. Locking? Limited Slip? English please?
10.) Skid Plates/Underbody Protection.
11.) Snorkel.

THANKS!
