Aside from the other answers, which are all great suggestions, if you have a smartphone try subscribing to French language podcasts. There are a lot of great ones available and they're free.
Just search for "French" in the iTunes Store and select "Podcasts" from the search results, then read the reviews to get the best ones. There were 40-50 selections when I checked just now. The one I use is called "Coffee Break French" and I can recommend that, but it's best to go through and pick the one(s) with content and at a complexity level that best suits your learning goals.
(Android Market probably has something similar, but I'm not familiar).
Listening to podcasts is a great way to supplement anything else you're doing because you have them on your mobile and possibly your laptop as well, and you can listen to them during "dead" time throughout the day like when you're driving, waiting in line or in the doctor's office, in the shower, etc. I used this very effectively and still do to learn Mandarin, and lately I've begun doing it with French too which, like you, I'm trying to refresh after several years of not using the language at all.
