Hmmm... if you break it down into the 1 inch per gallon rule then:
5 Cardinals: 5 inches
3 Lemon Tetras: ~4 inches
1 Gold Gourami: 6 inches
2 Gold Rams: 6 inches
2 Albino Cory Cats: 4 inches
So you've got about 25 inches worth of fish... it's the Gold Gourami that's going to get big. The additional Cardinal shouldn't kill you, but more Rams may be a bit much. You shouldn't do much else to the tank until the cycle is completed though.
Remember that Rams need really good water conditions, so if you were to get more, you'd need to wait a few more months, even if your Gold ones make it, though I don't suggest more.
I think I'm talking in circles, or maybe I just feel like I am xD
