With regards to the 3 main WS's you'll use, consider 1 point of STR to be equal to if not slightly more powerful than 5 points of Attack. Therefore, the difference in damage between Amemet+1 and Smilo+1 would be almost entirely negligable. You'd be better off just using Amemet+1 (or foragers, cerb+1 depending on your wallet) for both TP and WS.
And yes, Domaru is a total waste. Haub -> Haub +1, perhaps Osode for SA/SATA WS on especially high end mobs, but the difference will be minor.. and you'll probably find Haub +1 beats Osode for SA/SATA WS in most situations anyway.
