Welcome to the forums!
I am actually surprised yours came with a manual; I got manuals for some of the appliances, but that is it.
To plug into power at home, you need an adapter like this:
Walmart.com: Road Power 30/15-Amp RV Power Adapter Cord: Computers
Just be careful about what all you have running at one time. I find on 15 amp power I can run 1 of the following: microwave, electric hot water heater, air conditioning. However those all draw 10-13 amps so there isn't much room for anything else.
I will double check my trailer when I get home, but I seem to recall it saying where to jack it somewhere on the frame. I also keep a short 2x2 by my jack to be able to jack the frame correctly. The tire iron you need is a common 19mm/ 3/4". I had a spare from an old car that I keep in the trailer.
We also have a long running Wolf Pup thread that you might find useful:

On post #26 I have some of what I mentioned above for wattage; the one thing I didn't have there at the time was the A/C which draws 1250 watts on low, and 1400 watts on high.
