looks good.
if your gouramis are both male than the one that keeps chasing the other is establishing a territory, sometimes these do better by themselves. But if you do have one of each sex then adding the other will be good.
the cories will be a good addition, ive heard a lot of good things about albino, they only get to be about 3 inches at the max, so a small shoal (5 or more) would be good.
id watch out for overstocking, you will be very near by just adding a shoal of cories.
right now you are at:
ram-16 inches (adult size is 4 inch times this by 4)
loach-5 inch
gouramis-4 inch (6 inch with the addition of 1 more)
total=25 inches
since your tank is about 23 us gal this would be considered overstocked, but small additions would be okay.
neon tetras would be alright, maybe 7 or 8 of these.
