I just barely scanned the other posts, but I brewed my first batch a few weeks ago, and there were two things I did that worked great and were very easy.
1) I just left my kettle in the sink with water surrounding it and kept adding ice to it until I got the temperature down. A small bag from the grocery store should be plenty. Remember to leave the lid on.
2) I did a concentrated boil, so that all the extract and hops were boiled in about 3 to 3.5 gallons of water. The rest of the water was chilled in a fridge. When my wort was getting near 70 degrees, I dumped the cold water into the fermentor and then dumped in the wort after that. Mixed it for about 5 minutes to aerate and even out the temps and I was good to go. I forget at what temperature I mixed them at, but I think it was around 90F. Someone else might be able to chime in with a better number. You might want to do a quick search on adjusting your boil additions for a concentrated boil, but that is definately not necessary.
I'm by no means an expert, but I have read a lot and that was what worked for me. Also, I'm typing this from my phone, I apologize if something makes no sense at all, I'm sure someone will correct me.
