as said WW is a great starter jungler, start out with a cloth armor and 5 health pots.
get a leash from someone, if possible ask if they can hang out for a while and help kill the neutral monster if you are worried about it
most junglers tend to have similar qualities, most are either tanky/dps or very fast at doing alot of dmg quick (first to come to mind would be alistar and mundo for tanky dps... and for fast clearing would be either shaco nocturne or lee sin )
start at blue buff if your champ is dependent on mana usage then work your way around to red clearning out the wolfs and wraiths then hitting red (use pots as you see fit) once red is out look around and if you see a lane were the enemy is almost to your turrent that is a great lane to gank, try to call out a champ you want to be focused then run in and start trying to kill them (watch your health you are of no use to the lane if you are almost dead from your jungle)... this same process works if you go from red to blue just do everything as stated above just backwards.... if you dont use mana give blue buff off to mid lane it helps them big time
lastly a good build to go for is get wriggles lantern early game and go for gp5 items your goal is get the lanes fed not you (vary's from game to game i've seen a jungle lee sin carry his team within 25 mins)
i hoped this helped you
