Hi jjsolley, and welcome!

Here's a handy reference guide I put together for new Steemit users especially. It's simple and covers the most basic elements of Steemit that everyone here needs to know about, which are steem, steem dollars, steem power, voting power, followers, vests and witnesses. It also includes links to some very helpful external sites. This is some of what it covers:

• Steemdb (stats)
• Steemd (stats)
• Steemstats
• SteemDollar: your vote's worth - find out how much your vote is worth, based on steem power. H/t to @rymlen
• Steemnow
• Steemitboard - Shows your awards - by @steemitboard

And on steem, steem power and steem dollars:

• Steemit Vlog #4: Steemit 101 - Steem, Steem Dollars, and Steem Power - by @andrarchy.
• Steemit 101 - Steem, Steem Dollars, and Steem Power (YouTube) - by @andrarchy.
• Introduction to Steem Dollars (SBD) -by @dantheman.

I hope Steemit works out very well for you!
