you could start with a few hardier fish such as guppies be sure to get one sex, males are generally preferred as they are much more colourful, mollies are good but like guppies breed really easily, weather loaches, tetras and rainbow sharks are easy to keep, but the shark can be territorial with same or similar spices so best just to get one.
Their are loads or fish that are ideal for first setups, I would suggest the harder ones as they tend to have a higher survival rate for some less experienced or first time owners.
when setting up the tank it needs to run (without fish) for about a week when you can buy some hard fish and put them into the tank, just a few to start of with, this allows the filter to mature and raises the bacteria levels, these will keep the tank safe for the fish by breaking down harmful ammonia and nitrite into nitrate, this is remove during water changes every 2 weeks or so. After about another week you can add more fish and so one.
good luck
