This is probably the best Strange build atm, even if it is 3 months old
http://marvelheroes.info/build/3469/You can't really powerlevel in this game, although doing story mode is quite fast, and will get even faster each time you get a hero to lvl 60 (Each hero grants bonus xp, and it caps at around 200% (I think))
You can trade artifacts, runes, cores, blessings, cosmic gear and insginias. Although you cannot trade unique gear, Cosmic artifacts, legendary weps.
I have a lot of good artifacts that I could sell you. As for "Someone to Carry me on their Patrols/Danger Room Scenerios so I can get sexy drops." You need to pass the "cosmic trial" on your own, and then someone could help you in CDR.
