Definately get rid of the undergravel filter. Not only does it created surface aggitation, but creates a bad bed environment for plants. By getting rid of this filter, you will likely see in an increase of co2.
The eheim eccos are decent, the classics are better, Eheim 2213 is the one I would recommend. If you want to shave a few bucks, then purchase a Filstar XP1 (pricematch it a petsmart with bigalsonline.com printout of the product). I hear fluvals are decent, but I'm having issues with my 104 right now.
The light probably should be replaced eventually, but the filter is causing more problems for you. Right now you have a low - slight medium systesm, you will be able to grow plants slowly and surely, especially with DIY CO2.
Not sure what CO2 reactor/diffuser you have setup, but your levels will surely increase with the removal of the UGF.
