I do agree with the 10 gallon part! The bigger the aquarium, the easier it is to care for ^_^
However, Mollies can grow to be 5 inches each so I would scratch them, Clown loaches also can reach up to 16 inches so I'd scratch them as well. You could do: 1 Betta, a shoal of 5-6 Corydoras Habrosus (small enough to be happy in the 10 but still active enough) and a shoal of 6-7 Ember Tetras if you can find them! That would make a very happy tank indeed! Platies, as with most livebearers, are very messy and they poop everywhere terribly so I'd scratch them too if you want a nice clean tank.
Cycle is still a month's worth regardless of what size tank it is. If it's 2 gallon or 200 gallons, it still takes roughly a month if you do it right. There are ways to make it shorter like adding seeded material (filter material from an established tank from the LFS or a friend) or by adding live plants (although this is an entirely different world from fish and once you get sucked in, you'll never be able to return! lol). You have your choice of methods though if you take a look in our stickies you will find different ways to Cycle including Fish-In (a fish in the tank to feed the good bacteria), Fish-Less (usually using fish food or pure ammonia to cycle in less time ~2.5-3 weeks) or Silent Cycle which is using a planted tank to keep the fish safe.
It's whatever you feel comfortable with and we'd be happy to explain each of them after you look through the stickies ^_^
