Which FET should i buy, doesn't seem like anyone at the store was able to assist me... :\

You want an n-channel logic level FET.
That is one where they specify the on resistance Ron at a gate voltage of 5V or so.
Most FETs need 10V on the gate to fully turn them on.
Do not mix this up with a gate threshold voltage of 5V as this is the point where the FET just starts to switch on.
