60-70 Advice

My advice for you:

-quest in Terrokar until 64
-Go to Nagrand, Quest there until 66 or 67ish
-Run Some instances for much of lvl 67, and ding 68.
-Do BEM quests until 69, or even stick it out till 70.
-If you're not 70 from BEM, do a FEW quests in Netherstorm. This way you'll ding 70 with all quests in SMV and most quests in Netherstorm to do for gold.

this is my current plan, and I'm at 66.25-ish

as a boxer gold is the least of ur worries

u can 1 hit anything once ur geared so farming ANYTHING should be a cake walk.

Step 1: Ignore AH for any Buying reason.
Step 2: Loot everything. Sell Greys/whites/non-"High demand suffix" greens(or DE if you have an Enchanter, and shame on you if you don't)
Step 3: Don't buy at the AH.
Step 4: Avoid spending in the vicinity of an auction related "house".
*cough* ;)

My first 70 was my Hunter. I had slightly over 1k at 70, enough to get flying training + mount right off the bat.
My 2nd 70 was my Druid. Flight Form was nearly free at 68; I had about 1200-1400g at 70.(Which went towards epic flight form eventually)
My third 70 was my Rogue. Lvl'd with my ex's warlock from 60 to 70. He transferred WITH 900g from pre-bc(My ONLY char to EVER EVER EVER go above 300g and that was AFTER an epic land mount pre-bc lol) so he was fine at 70 for getting flying training.
My 2 Boomkin clones are 66 currently. They EACH have 1600ish gold. I blame 2 things for this: Knowledge of Outlands from 3 previous run-throughs, and not needing to buy nice gear off the AH like I did for the other 3. Flight Form will be near-free for them too so Epic Flight shouldn't be far off ;p
My 38 Shaman currently has 200+ gold. He still has lv38+40 training + mount to get though so he'll probably be back down to 100 or less by then. The other 2 shamen are around 100g too, One is a Miner/JC, Too is an Ench, Three has no prof yet, may go skinning to feed Eteo's LW.

Bottom line is, greys = win, AH = consider it a SElling Only house ;p, Live on quest gear; it's sufficient till 70. I can't really give many more tips than that; besides "Don't enter outland till 60 so you don't waste boosted exp gain from Silithus/Winterspring nor waste Gold-earning quests at-70 in Nether/SMV" ;p
