Do this, don't ask for a list.
Infinity is incredibly well balanced. You're not going to wind up with models that are bad, and when you're learning, you've got more important things to worry about than making a list that can complete objectives in ITS (objectives are the most important concern when making a proper list).
My general advice is - look on the official website at the models, and figure out what you like. Jump on the official army builder (on the main site, at the bottom, there's an option called Infinity Army), and play around with making about a 150pt list with the models you like.
Once you've got that 150pt list made of models you like, seek out others at your
FLGS or amongst friends that play and play a few games with that list. Just get used to the order system,
AROs, face to face rolls, etc.
Once you're comfortable playing the game, then look at expanding what you have for objective games.
