Newbie encumbrance

[Rainflush]

I made an Erudite Paladin (ridiculous I know, though I can tolerate an inferior character just to be different) who is presently level 11 and more or less constantly encumbered despite carrying very little save his equipment, bandages, and arrows. Could anyone suggest some strength items or perhaps even weight reducing containers that could be readily acquired by a character between levels 10-15 or so?
