I just did the level 60 Ishgard items on one of my alts, whose jobs were in the 61-64 range. She's leveled up and upgraded gear since so I don't know what her stats were at the time. I think I remember total CP being 385 on my non-specialists but I'm not positive.

I was using the Handmasters scrip accessories, Chimerical Felt Doublet of Crafting (NQ). Ironworks Cap of Crafting (NQ) and a random mix of level 54-60 gear in the remaining slots. All primary tools were level 57. Items that could be melded were melded with Cunning > Command. On the items where i could only add 1-2 additional CP, I would meld for control in the socket then overmeld to get the last CP. Otherwise, I put CP in the socket and added a Command III for one overmeld since I already had several and they're cheap. For food I was using NQ Beet Soup.

At level 61, I was getting 700-1000 rating pretty consistently. I started with Muscle Memory > Inner Quiet >Waste Not II. I would use Basic Synthesis on Normal/Poor Conditions until I was one Synthesis step from completion and Precise Touch when Good. I used Master's Mend to restore durability after Waste Not expired. If I remember correctly, I would get 5 Basic/Precise Touch actions (6 on my specialists) plus had enough excess durability to squeeze in 2 Hasty Touches until I was down to 74 CP or slightly over. I finished with Great Strides, Innovation and Byregot's Blessing then a final Basic Synthesis.

As long as your gear is all at least level 60, you shouldn't have any problems with minimum craftsmanship. From there, meld to max out CP then add on what control is comfortable for your budget.
