I live in SF and the temps here seem to be perfect for the sikorae. I don't use any temp control other than I would use for comfortable living (i.e. turning on the heat in the winter). Although, I do believe that my geckos have converted to this hemisphere's climate. Because my female laid from may to september last year, this would be their normal dormant period in madagascar. She did however start laying in marrch this year, but we went through a bit of a heat wave in late february, which semms to have triggered some breeding activity.
As for the rest I would agree with Matt and Jason, big tank, lots of natural plants, and UV light. And keep an eye on your female during the breeding season, because I didn't find eggs last year until her third clutch then found five at once. Since then I haven't missed any, well that I know of anyway.
If you want more information feel free to contact me by email. If you want exact temps etc.
here's a pic of their enclosure.
