Hi Eric.
I think everyone else has covered the basics, beyond checking that it has improved your photography so you don't need to return it!
You can find manuals for the camera on the canon sites, download it to your phone or better yet your table if you have one, that way you can search it for info you want and easily bookmark pages you will visit frequently.
It is possible to find most of, if not all, the manuals without the COPY watermark if you find it too distracting.
I have the manuals for my cameras on phone and tablet, I tend to grab my tablet during lunch and if the 3G signal is not reaching and I can't read the forum, I will revisit a manual and refresh myself on some of the less used functions.
Cheers Graham.

And read the manual. Especially the AF section. You'll probably end up re-reading it a couple of times a day for a week or two while you experiment with the AF modes & selections before it starts to become automatic.
