A quick back of the envelope calculation suggests that you have no chance of qualifying for EXP, which is far more valuable (if you fly AA metal) than BA gold. However, if all your long-hauls are in WTP, you may just squeeze by and get 800+ TPs. In which case, you could search for 'euro-cheat' on this board. I am not necessarily condoning it, and its days may be numbered, but it might mean that you might be get BA gold status for <50k flown miles a year.
In terms of redemptions: as already stated, BA miles are essentially worthless for Y redemptions (unless booking at last minute), so if you e.g. have a family and want to redeem for all in Y, BA just isn't worth it. Even for straightforward J/F redemptions, there isn't a huge difference between AA/BA, even when redeeming on BA, and if redeeming on AA, AA wins hands down. But BA really comes into its own for UG of WTP to J, and for the BA Amex 2-4-1 (but the card is fairly pricey).
