I'd say go all out and get the Archaea lamp. It's the best bet for a Mini-M behind the Solar series, and provides the same light.
I also have to agree with zeldar that a Red Sea Nano is too underpowered for the Mini-M. I had one on mine when my canister was down, and it really felt like there was no movement at all.
I don't know what your budget is, but if you can afford to spend a little bit you can get the ADA Co2 System and the parts to have it take up zero counterspace (you can hang it from the side of the tank) Or if you go the DIY route, I've found Vitamin Water bottles work great for nano tanks and take up very little room.
I don't know if you're looking for suggestions for plants, but with 26/27W over the Mini-M, you can grow just about anything. I've currently got Glosso, HC, HM and H. tenellum growing in mine, all carpeting. Anubias nana 'petite' is another slow grower that seems like it was made for a nano tank.
