Cyclocross - CX and SSCX races and training

I have an old frame that I'm planning on using for some sscx, can anyone recommend a good usable gear?

i know you might meed to change up or down a bit depending on terrain, but a good starter guide would be useful. I always used 32x16 on my ss mtb, but how does this translate to 700c wheels?

I'm doing exactly what you are planning and am gonna run with 34x17 for a 2:1 ratio, or 54GI on 700x32s. Bike nearly finished, stoked.
