Well, if you do go with the sk, then gearing one up is not too difficult..... I leveled one up about a year ago, and this is the upgrade path that I followed.
- buy/camp 1hs and 2hs from Acrylia Caverns, 1hb from CoM, and just browse the bazaar for a 2hb and piercing weapons
- you also looking for WoS drops from the bazaar- most are recommended lvl 66, so you can equip and "grow" into the gear
- Armguards of Repentance sell for around 1-4k
- Look for Magnetic gear
- camp yourself a haste belt from fellspine
- camp/buy a sarnak battle shield
- buy /make skinspike potions lvls 1-5
- buy a Blade of Disruption for later
Level until 55- preferably in old / new hotzones for the nifty drops along the way
(Head to griegs and pick up the melee earring, the ph is a human model that paths towards the courtyard near the Scarlet Desert zoneout)
Pick up an ornate bp mold if you can- the clicky on it will do you well until your mid-60's.
Level until 65, knock out run3 along the way- then grind some tanking aa's at 65. (This is the trick, the more aa'ed your tank is at 65 and on, then the harder content you can box.... obviously.)
At level 66, there should be some new bazaar upgrades available that are required lvl 66.
Box the arcstone firetails for BP and Leg marks for your sk, and a BP mark for your shaman (its a great Oh shit! clicky).
Head to relic at 68 for the earring and ring quest.
Do Dain 1/2/3 for the shield / aug, and hit up the icefall bears at 71 for an even better shield.
While in Icefall, wait for a BP mold to rot..... it's going to happen.
The Spirit Hunter Cloak quest will also last you forever, you will be able to box the Tree mob, and many other pieces will probably rot while you are hunting your bp /leg marks....
Outside of this, just collect up plat along the way to fill in any parts through the bazaar. Also, if you can find /organize a PoTime raid- do it. PoTime is still a golden candyland for tanks due to the high ac values of the gear (AC>HPs).
You will also eventually be able to box most of the sk's epic 1.5 except the murkglider school leader and the final fight in WW....
