Hey there, welcome to TPT and your new obsession :p
The lights should work fine, the red bulbs are a plant specific waveform supposed to promote growth and bring out colors in your fish and plants.. you can decide on your own if you think they work :P I swapped mine out for a 6500 and a 6700K to go with my 2x10000K I already run. The 10000k will be fine. Some people prefer 6700K because it's a little more yellow-ey and looks the same as normal daylight from the sun but I tend to like the 10000k spectrum more for the cooler look it brings. Both will work fine for growing plants you may use any combination of the roseate bulbs or 5000-10000K but most people stick in the 6000-10000K region.
I'm assuming you mean a drop checker to check the CO2 levels, and if so then just wait until you get it. However I'm going to think that 1bps will not be enough for your 31G, I have a 36G bowfront with a (what I consider) moderate to heavy plant mass and it takes 4 bubbles per second diffused into my canister filter's intake (so probably upwards of 90% effective diffusion) to maintain a nice light green-yellow on my drop checker (green on a drop checker is usually a good estimate of about 30PPM co2 in your tank which is what you should be shooting for generally).
I'd say quit with the disposables while you can and upgrade to either a paintball Co2 system or even more financialy friendly a 5lb or even 10lb Co2 system. I have a 20oz paintball tank with a quality regulator and needle valve on my system and I usually get about 2-2.5 months per fill on 3-4bps running at 9 hours a day with solenoid. You'll be burning through those little cartridges so fast to maintain adequate co2 levels that in 2 months I'd almost guarantee you'd have spent more on cartridges than the startup cost of a good Co2 system. You can look on fleabay or even the swap n shop section here (put up a wanted ad) and get a great affordable deal if you can find someone else that lives in UK as to avoid shipping costs from the states.
Anyways, best of luck and ask any more Q's if you need.
