All the information you have on propanol is correct. Polar/non-polar is not a black and white distinction; there are areas of grey between polar and non-polar. Propanol can be considered polar because of its OH group, but it also has a sizable non-polar alkane region. So in terms of polarity, it's less polar than water, but more polar than a lot of other organics like dichloromethane or hexane.
As for the geometry, you are also correct. The carbons will have a tetrahedral geometry about them while the oxygen will have a bent geometry.
