Here's some game play tips that made my life easier long ago.
For PVE weapon power should be set to 100+, 90% of the time.
Change your throttle control to the scroll wheel on your mouse (if you have one).
Place zoom as "control + scroll wheel" so that you can still do it if required.
Get rid of the "r" key's default function of "full throttle/full stop" and replace it with the "balance shield" key.
Those things will help game play a lot till you master key binds and more advanced combat strategies.
