Why don't you just create a magic item that replaces your arm (a graft, even), granting the warforged's 1d4 slam, +2 Str, and the ability to embed 'forged components in your arm. I'd put that at -2 HP, 9500g.
Subcutaneous plate for -5 HP and 12000g, granting +2 natural armor, DR 1/Adamantine and the ability to embed warforged components into your torso.
Replacement leg, +4 Balance and Jump, +10ft speed, and the ability to embed warforged components into your legs. -3 HP and 4500g.
If you don't want to actually replace a body part or two (which I think should be the only way you can embed these components, since that's what they're meant for...), you could create a bracer, greave and breastplate that allows you to attach the components to the outside and have the same effect.
