Ouch... Yeah, low-STR can do that to you.
I believe there are some DMs, or a common house rule (i forget now which one), that allows you to ignore armor/clothing and weapon weight for encumbrance purposes - or something like that... If you can get your DM to go for that, you're golden. Otherwise, handy haversacks, belts of many pouches and other forms of extradimensional storage items are your friends.
Also, you may consider armor abilities like "Easy travel" (MIC, p.10, +1,500Gp) that allow you to carry up to medium weight as if it were light. I remember something about an ability or item that allows you to double your weight capacity, but can't seem to remember it's name. I'll post here if i do...
EDIT:
Got it!
BELT OF THE WIDE EARTH (MIC, p. 204, 8,000GPs). Part of the Raiment of the Four, this belt doubles the weight capacity of the wearer. If you manage to reverse engineer the item to remove the teleport ability, you might end up with an item costing close to Gauntlets of Ogre power, but with a better effect.
