If your tank is the ususal 5 gallon AG size and shape, then I would highly suggest just upgrading to a 10 gallon. It would be like what, 10 bucks? Trust me, you'll be frustrated with theb 5 g's small space, and I'm sure your ram would appreciate the upgrade. All your old equipment would work fine, and it would justify shelling out the bucks for a *good* light.
That being said, I use only 1 of the CF mini aqualight minis on a 10 gallon, and it grows plants well. I just make sure to plant the hi-light plants directly under the light, like cabomba, some swords, etc.
In the margins, I put the lower-light plants: anubius, java fern, moss, and 3 types of crypts.
I've had the tank before with just normal strip lights, and the growth was nowhere near what it is now.
On your 5g, I would go ahead and use just one CF aqualight mini.
If you go with the strip light, you'll need to stick to lower light plants like the crypts, anubius and mosses.
