My opinion, this is how I'd gear out: Any of the 220 HQ accessories that you can get hands on, you should. They'll carry you far. In your case, especially look at wrist and maybe one ring. If you have extra gil, I'd buy the crafted HQ body piece, too.
Today: Farm your 450 lore, buy lore head piece (Bis?) 80+450= 530-495=35 Midas, I'd get: M1: pedal M2: pedal (there's your feet gear) M3: crank M4: shaft
Tomorrow and upcoming week: Farm your lore; save them. 35 + 450 =485 M1: chain (belt) M2: bolt (acc) M3: crank (hands completed) M4: shaft
At this point you'll be almost fully 220-230 left side other than body, and fully right side accessories, assuming you were able to buy some crafted. The two lore pieced you've purchased (in my opinion) are BiS so you're already well-invested there. Anyway, just something to consider. Anyone w/ more NIN knowledge (which is ANYONE) please edit this.
Not much to add really. Just whatever he can afford in crafted gear (BIS or not) will go a long way in immediately pumping up his main stat. HQ of course.
