I'd say, save cps for ninja first (you will gain power on dailies anyway, even though its just a little gain), get the lineup you want, the solid one. After that go for power.

As a F2P and a new player myself, I planned on saving 20k cps first then spend it for cat deals, on what I spend it depends on the events that come together with cat deals (actually I want to get jonin minato, but then I think I dont have to).
