As far as the planes looking like small dots, you may want to try the Zoom features out.
Z - Toggels Zoom on/off
[ - Zooms IN
] - Zooms out
I have these 3 keys mapped to my joystick, I like to zoom all the way in on an enemy plane when i am saddled up and ready to shoot, Some people like to shoot with the zoom off, I find i am alot better shot if i am zoomed all the way in, but with that level of magnification if the enemy is close (under d400) and makes an abrupt move and gets out of your direct line of sight you can get disoriented very quickly, when that happens i just hit the Z key to turn the zoom off untill i can saddle back up on him and then i will zoom in again.
