Hey hammer!
We need a few more details first. What aircraft and to what airports are you flying to? Did you file IFR?
It is important to know whether or not your arrival airports have a ground frequency. If they do, then you switch to ground upon exiting the runway and request taxi clearance.
If it's an uncontrolled airport, then the taxiing is up to you

Just try to find a ramp area and park it there.
You have a few options for refueling-most of the small airports have a refueling station, marked by a bright yellow square. Taxi into this square, and voila! Full fuel (if it doesn't work, try shutting down the engine, or putting on your parking brake).
However, there's another, much easier, and, more often that not, more realistic way to do it-hit alt, 'a', then 'f'. From this screen, you can specify exact amounts to fuel individual tanks.
Hope that helps
