Re item 2 I have had success using satellite tv splitters that provide for dc pass thru as gps signal splitters. I can't argue with the price and being able to buy them at home depot.
Re item 3 I ground the mast for gps antenna, and the shield of the feed line. (I already have ground system for various radio antennas.) If I lived in an area with lots of lightning i'd take more precautions. I've also bonded the Antenna grounds to the electrical service ground, which may or may not be a code requirement where you live. (Disclaimer don't take this message as advice.)
