Well, I'd leave it in primary for at least a few more days anyway.
The yeast will do very well at those temperatures. With the one I'm drinking now, I left it in primary about 3 weeks, then dropped the temperature to the high 40s. It really came out well!
I kegged this batch, so I didn't use a secondary. You can if you want, or you can keep it where it is for about 3 weeks.
