Plateau at level 23

At level 23, I finally hit my first major XP plateau. There aren't very many quests left for me to do; right now I have:

In Search of Thaelrid
Knowledge in the Deeps
The Only Cure is More Green Glow
Digging Through the Ooze

The first two are in Blackfathom Deep, Green Glow is in Gnomeregan, and I don't think I can do Ooze via pickpocketing, but I'm going to try (there's at least one rogue quest where you can PP oozes for quest drops and also kill them for quest drops, so it's possible I could get whatshername's bag by pickpocketing oozes...)

There's a quest I haven't picked up yet in Forest Song, and one I might be able to get by pickpocketing Gruff Swiftbite, a rare spawn near Hogger. I've PP'd him a few times, but no gold schedule yet...

So, I've respecced from Subtlety to Combat so I can get 2 points in Improved Sprint and 2 in Endurance, which will help in WSG and AB. I've also gotten a net-o-matic, cloaking device, parachute cloak, mind control cap, rocket helmet, harm prevention belt, minor recombobulator (which I can make) and gnomish rocket boots (with slight speed increase enchant). I also picked up a pair of Swift Boots for only 1 gold in the AH (which I can't wear until level 35); I put speed increase enchant on them, too. I still want to get the discombobulator ray schematic (I have the delta card, but Gnomer is too dangerous I think).

The Charred Vale in Stonetalon Mountains is the absolute best place for a self-twinking lowbie to mine. Mithril and truesilver nodes, and most are far enough out on the edges to not aggro mobs. My mining is 247, I could mine small thorium veins. There's one in Felwood near the Ashenvale border that I might try to get, or, since I drowned myself off the coast of EPL so I could res at Light's Hope Chapel (to get to Ghostlands for more exploring XP), I could fly to Light's Hope and maybe find a node.
