Thanks for the great suggestions, Gohaken.
I don't know if I really want to replace any of my feats, but that Adopted trait looks really good, as does the Titanic armor. I also will be getting the gauntlets, as well. It was things like that I was talking about in looking for.
As for the traits I have now. Armor Expert, Giant-blooded and I can't remember the name now, but gives me +1 on Profession checks.
But I can certainly see myself swapping out Armor Expert for Adopted.
I definitely planned on getting myself a Belt of Giant Strength later on. Part of my anticipated +21 CMB is having a +2 belt (will of course go higher than that eventually).
I will probably be getting the Ioun stone (Thorny), as well. Thanks so much for all the great suggestions, Gohaken.
And yeah, I really like the Titan Fighter, looking forward in giving him a good go. :)
