The can lights you want for insulation are called IC. We use them regardless of insulation or not because they are cheaper than non-IC. In general, we keep about 6 cans per switch/circuit.
Joist cutting is bad joo-joo so, don't even think about it. If your cans won't line up perfectly, then readjust them.
Home Depot usually has "Contractor pack" can lights which consist of six can lights and six trim rings. They are alot cheaper to buy together, rather than seperate. If you have to, ask for them, because it can be a savings of over $20 bucks if they have them in stock.
