First off welcome to the forum Shawndee!!! Glad to have you with us.
Now for your question:
Yes using no follow links can be very helpful for increasing your traffic back to your site, but it might not actually have much SEO power behind it. However, having a mixture of both no follow, and do follow links seem to be better in googles eyes and can help to avoid having your site penalized.
Hope my answer helps your question
