I've been taking a look, and my recommendation would be to concentrate on your natural attacks. You've already got 2 claws, and get to use your rear claws on a rake while airborne. Grab the Dragon Tail feat (prereq: Dragonblood subtype--- your DM might require you to take a feat to qualify, or not--- it seems kind of iffy to me) for a 1d8 tail slam. Then you'll have 3 natural attacks, and qualify for Multiattack and Improved Multiattack.
Seriously consider picking up the Half-Dragon template via the "Template Class". It'll give you another natural attack (Bite 1d8); another +8 to Strength and another +2 to Int, Cha, and Con; +7 extra hit points (from the increase to racial HD); another +4 to natural armor, an energy immunity, and a breath weapon, plus the coveted Dragon type.
You've already got a great BAB, plus your enormous Strength. If you focus on natural weapons, you could potentially have 6 attacks (2 claws, 1 tail, 1 bite, 2 rear claws) at your full BAB.
If you go Half-Dragon to get the Dragon type, you'll be able to qualify for Rapidstrike (and later Improved Rapidstrike) and get even more attacks with your claws.
That would be 2 claws +(BAB), 1 tail +(BAB), 1 bite +(BAB), 2 rear claws +(BAB), 1 claw +(BAB-5), 1 claw (BAB-10), 1 claw (BAB-15) and 1 claw (BAB-20).
Remember that you get to add your full Strength bonus to each of those claws, too.
Ten attacks isn't too shabby.
