Help, Please

OK, I'm an Idiot. Now that's out of the way.
I need a step by step process to get a downloaded cab to my TP. Believe it or not, I have done this before on my first TP. I found it somewhere in this forum and installed the volume fix cab file. Now I want to install the weather cab that has all the cities and a game and I'm lost. Before you tell me to search, I have. I have read hundreds of pages over the last few days, my mind is mush. My wife will find me in a corner in the fetal position mumbling something about buying a phone smarter than myself.
This is my first smart phone and I really do love it. I'm jut not real computer savvy and am afraid to mess up the phone.
If I could find one of you smart people near Rochester, I would just give you the phone and have you install the stuff I want.
So if there is anyone out there willing to give me step by step instructions for installing the cab files I listed above and how to change the icons at the top of the screen, I would greatly APPRECIATE it.
Thanks for listening and please take it easy on me, I'm in a fragile state of mind.
