I use an Asp Explorer for smuggling. The main reason it's a good ship is because the heat signature is very small and it runs cool out of the box. I very very rarely get scanned and even rarer get caught. Every now and again I'd get a federal ship up my chuff, submit to interdiction and boost away. AspE is a pretty fast ship in normal flight mode.
For docking, always approach in super-cruise from the planet side, this will line you up more or less with the letter box.
I dock at 100% throttle until I'm about 300 yards from the letterbox and then set to zero throttle and burn out the rear facing thrusters - I use 3A Shields just to prevent damage in case I hit the letterbox or back of the station... it happens every now and again...
Exiting the station full power and boost out of mass lock, FA-off to face the jump point whilst still moving in a straight line away from the station, then FSD, FA-on, 100% throttle, boost, gone.
