WotLK pvp gear mage

[Dardenen]

Hi guys,
I'm here cause i'm pretty new in WoW (i started playing one year ago) and i need help. I have a mage, just hit level 80. What now? How am i supposed to get a pvp gear? How can i get more emblems of triumph? Where am i supposed to buy the gear? How can i make more gold? I'm questing in Icecrown right now, but it only gives me gold or gear that i don't need. Explain as simple as possible please, no abbreviation like "TOC" or "ICC" cause i wouldn't understand lol.
Thank you very much.

Beginning:
Gearing: RDF (HC) & questing for reputation items.
Gold: You get gold from quests, unless you wish to farm and sell stuff via AH.

After:
RDF HC provides some PvE gear that you should take, to get RDF's done quicker.
Do Forge of Souls, Pit of Saron, Halls of Reflections runs as well for bit better gear.
EoT can be used to get furious set, if you choose to do so. Or PvE pieces.
BG's for honor to get gear gear.

ToC = Trial of the Champion/Crusader. ToC 5 means a 5man dungeon; 10 is a 10 man raid; 25 is, you guessed it, 25 man raid.
5 man provides 200/219 ilvl (Normal/HC)
10 man provides 232 ilvl gear on normal, on HC 245's.
25 man provides 245 ilvl gear.
ICC = Icecrown Citadel aka the raid we all love.
ilvls: 10 N 251's, 25 N 264's,
