You aren't a noob, trust me on that one. Tips are hard to give since everyone has a different style of play. If you main the Tommy, then I suggest getting in those 'in yor face' gunfights where the two people circle around eachother. Those are my favourite, but it starts to become chaos.
If you prefer to fall back on your teammates, and you are really indifferent to whether you die or not, then i suggest using the MP40 since it is a great gun to spray bullets at your opponents. Plus it makes it easier for your teammates to finish those opponents off.
It all depends on the gun you use.
