There are a set of decent tutorials on the Lencarta site - they're obviously oriented at techniques, but should give you a reasonable idea of where to start, and what is possible from different sets of gear.
Frankly, in my exerience many of the people who are offering tutition to beginners (and often to people who are not beginners too) are beginners themselves, and have very little to offer.
These tutorials should get you thinking in the right direction. Some are pretty specialised but most are not, and should be helpful. Ignore the subject material, because with the tutorials that I've written personally, I usually go for still life subjects, which isn't your subject of choice - but it doesn't matter, the principles are the same. I go for still life because because when I photograph people they
1. Want paying
2. Everything needs to be planned in advance and the shoot can't be fitted into odd moments
3. Still life subjects don't complain, don't want tea breaks and keep still.
There is one tutorial that may be specially useful to you, at least to start with,
Getting Started with Studio flash.
http://www.lencarta.com/studio-lighting-blog/10/getting-started-with-studio-flash/#.WEWNDn3WGkx I haven't included any example photos but it does go through the basics in enough detail to make things simple.
Other than that, just experiment and see what you can achieve. When you run into problems or need questions answering, just post on here and we'll all do our best to confuse you
