In my experiences I have found gouramies to be a very hardy fish so they would probably be a good fish to start with. Gouramies are territorial and chase each other all the time. I never see them biting or nipping though.
I've never kept white clouds so I am no help there but I can tell you that keeping snails alive is an extremely easy job. Shrimps are fairly easy to keep too. Other fish that I consider to be good started fish that don't cost much and are peaceful are zebra and leopard danios and platies. I think they are pretty good looking too and platies can be very colourful.
