A few Woodstock Low Power questions

[Dave Shaffer]

Stellarium is your best bet! (Take it from a real astronomer! Why reinvent the wheel?)

GPS accuracy is variable. 5-10-15 meters is about as good as you can hope for from a simple one-channel unit, especially if multi-path occurs, and on days with ionospheric disturbance. If it uses something like WAAS, you will get better accuracy. A few meters is certainly good enough to tell you where your telescope is.

If the sky is clear enough to observe, you should be able to see the North Star (assuming you are in the northern hemisphere) - that will give you north to half a degree.
