If temp control is an issue you can always make a swamp cooler. Search the forum for ideas. I have a cooler in the garage filled with water and large ice pack. I live in WA so it rarely gets into the 80s. I can usually keep the water temp around 65 - 68 degrees.
My wife says that as soon as I buy us a new refrigerator I can use the old one for brewing.
^this. And yes, the yeast can clean up SOME of those high temp off flavors. Leave your beer in primary for a month or so, dry hopping for the last week or so. Then let it bottle condition for about a month. You may still have off flavors, but they'll mellow. Being a hoppy brew won't hurt either!
