Hello Lynna, congratulations on your accomplishments. I am rather new to the game as well.
Check this out, some great pointers from a couple guys who made the dream happen by using social-marketing. Man it is overwhelming at first.

Just make sure to get these three things all working and synchronized to revolve around you and lead to your main site, for example an amazon author page.
1)Twitter
2)Facebook
3)Blog
A really easy tip I learned from a "How To Blog" eBook from Amazon is this..
Visit two blogs every single day, well working day, and leave some pertinent comments. Make sure they are blogs in either your target audience, or the eBook community in general.
Tweet something at least 5 times a day. Retweet stuff, tweet informative things though not only just self promotion. I use my twitter as a way to advertise other peoples work, blog articles about eBooks, current events having to do with the technical aspect..etc
Post or comment something on face book 3 times a day.Join groups, give good advice, do anything and everything you can to help other people be successful. Social-Networking is about forming personal, one on one relationships. The more you can do for other people, to help their books sell, the better it will be for you. You are not selling anything, remember that, *wink
Write a blog post once a work day.
As you get used to it, and I am still new myself, it gets quicker and easier.
I truly wish you the best, may all your works bring you your dreams and then some, may your cup run over.
Cheers!

p.s. Here is a blog/social-networking guide I bought, it was helpful for me.
