When it comes to polar alignment...for visual, so long as your mount is pointing more or less south as above, Synscan will calculate your mount polar alignment error during your star alignment and compensate for it. If an object doesn't seem to be in the FOV, use your finder scope (that you aligned earlier) and use the direction controls on the handset accordingly.
In the latest Synscan software versions there is even a polar alignment routine, that you can activate following a 2-star alignment, and it will guide you through adjusting your mount to be more accurately polar aligned. It's worth doing, and it gives you good experience with adjusting your mount bolts and seeing what difference it makes.
Unfortunately, unless you have an observatory and can leave your mount setup permanently, you will need to setup and takedown every time. However, it does get easier! There are little tricks you can do...for example, once your scope is balanced, use a marker pen to put a line on the scope dovetail so you know where the Dec balance point is, likewise with the counterweight on the counterweight bar, so you know where your RA balance point is. This only works with the same scope, accessories, etc, but you get the idea. It will take a long time the first time you do it, but it gets easier and quicker with practice
