Like AnthonyH mentioned, it's best if you are going in there blind to go ahead with the Siamese cable. If the power pair isn't needed, it just won't be used. Come to think of it, most Siamese RG59 is 95% braid anyway, so you probably won't be able to buy it any other way.

22 gauge solid for basic RG59 with 95% braid should be fine unless the runs are unusually long. If so, then bump it up to 20 gauge. The 95% means the coverage of the braid, meaning that there are 5% worth of "holes" in the braid. That's fairly typical for CCTV, so any supplier will understand what you want.
