Fermentation temp would depend on the yeast you're using- generally 50 degrees or so.
Lagering is a different beast. That happens after the primary fermentation is completely finished, and after the diacetyl rest (if needed). Then the beer is racked to secondary, and the temperature dropped 5 degrees per day until you are at lagering temperature. You can lager at any temperature you choose- I usually do 34 degrees for 8-12 weeks. This gives a much smoother lager than those done at slightly higher temps.
Frozen packs in water with a t-shirt might work just fine, as long as you can maintain a decent lagering temperature that doesn't fluctuate. I do mine in an ice cube cooler with a styrofoam lid that I made so that the airlock pokes through. I have an ambient temperature of 48 degrees, though, in my basement in the winter, so it's easy to get it to a steady 34 degrees for the lagering.
I'll see if I can find a link from howtobrew.com for some good lagering info.
