[APD] Reversing day/night, Tank too hot, CO2 for day & O2 for night

Hello.  I set up my heavily-planted, 30 gallon freshwater tank about 2
weeks ago.  I use a 96W bulb 12 hours a day and a CO2 kit.  I have an
undergravel filter, external biowheel filter, and a powerhead.  I have
several questions & would appreciate your advice.  :)

1) I am thinking of putting two different lights on a timer so to have a
20W bulb running 2 hours a day (1 hour in the morning, 1 hour in the
evening) and the 96W bulb running 10 hours a day.  I thought this could
mimic sunrise and sunset, in a rough way, so the light change won't be
so sudden for my fish.  Is this a good method?

2) The water temperature is 27.7C to 28.4C.  Do you have any thoughts on
how to lower my tank temperature to 25C or 26C?  (Lowering my home air
conditioning is not an option for me.)  I noticed that the lower
temperature is generally towards the evening, so I was thinking of
reversing the day for the tank by wrapping a dark cloth around the tank
during the day and perhaps having a floor fan angled to blow on the
front of the tank and using the hood lights at night.  Do you have any
other ideas?    

3) With my heavily-planted tank, I was thinking of having the following
fish: 5 Chinese Hillstream Loach (aka: Borneo Sucker, Hillstream Loach,
Hong Kong Pleco, Butterfly Loach) and 12-15 Guppies.  I'd like to have a
pair of small Gouramis or a pair of Killifish and a 6-8 member school of
either Cardinal Tetras or Harlequin Rasboras.  However, would this be
too much?  Should I just stick to the loaches and guppies?

4) If I use the CO2 during the day, should I use additional aeration at
night to increase the oxygen?

Thank you,
