ok here it is!
quick summary:
after getting rid of that awful rotting plant smell I decided to upgrade on a couple things.
a new flourescent hood, a new 50w heater with a visible thermostat by Proquatics (works nice), a new power filter (Marineland Millennium 1000; also very nice).

I was also lucky enough to find some bio-spira and used it. A bit expesive though $11.99 for 1 oz! this better be good
heres a link to that

I poured a 1oz. packet inside the tank and into the bio-grid filter plate (venturi valve full on to give max air for bacteria growth)with at the time my single, very cool-looking, blue Betta. I monitored the water chemistry for the next 3 days and saw an increase of ammonia and a drop in ammonia then an increase of nitrite and its gradual drop. Seems like the bacteria were taking hold and my temps and pH were constant: 76F and 7.2-7.3pH
(tap water here in so. cali was 7.6-7.8pH, used pH down to soften it in seperate clean and empty milk jugs)
I then went out and got 6 neon tetras, one died, but the rest are healthy
Then waited some days and got a cory with 4 ghost shrimp
found some bio-coat and bio-blend foodand got them and used them since i was kinda impressed with the bio-spira. The bio-coat seemed nice to have here is a link to that:

so far only1 losse of life then neon tetra, 10-20% water changes every other day, daily chem readings.
My son and I like it very much and thank all of you for all your wise advice and suggestions. Wouldnt have gotten anywhere without the reading up on the tons of info available on the net.
Overall, I think a successful newbie tank that me and my are quite proud of
PS the betta is hilarious! with his new neighbors I was worried about his temperment but he seems to love investigating the other fishes and the cory is a valiantly cleaning in and out of the caves I think I will get him another cory to keep him company and then my tank will be maxed out for stocking.
in a couple months I'm going to try my hand at a planted 20-30g gourami tank, after I save up some extra cash
here is a link to than plan of mine
