My 2007 Sky Redline coollant temp goes up to 132 degrees when I first start driving it on cold days. Fan runs, but temp rises from 210 to 235 before cooling down to 201. Is this a sticking thermostat? Doesn't happen on warm days.

That is the first thing I would check. Also, make sure the coolant is strong enough that it doesn't freeze below 32°F.

I think that is a cheap and good place to start. Something tells me it is sticking.
