I cannot add much more, but I'll tell you what I tell other newcomers: it's hard to play the control role when you don't know the metagame. Once you understand which decks can you find and how to play against them, often is better to play less interactive decks. Aggro or combo decks seem the best approach, though infect has the problem that Matt pointed: there are lots of played cards that interact with it. Similar for reanimator, another decent deck from legacy, but suffers to much from graveyard and creature hate.
Combo decks (Storm, dredge, oath, turbotezz, academy) can play very aggresively and focus on your own win, not hampering the opponent. Humans, ravager MUD or Eldrazis play proactive threats and shouldn't be too much troublesome even for a new player (although it's important to understand the order of plays), but they are more interactive. So, my advise is to pick a combo deck and try to win fast games while learning about other decks.
