15 amp fuse is the normal max for bike accessories.
The GPS draws a miniscule amount, the bike won't even notice it.
Air pump is presumably only running with the engine off, so it's not the alternator that matters but the battery size. You should have no problem blowing up a tire or two, assuming a decent sized 12V battery. (you don't say what bike so I can only guess)
There are some advantages to using the BMW plug system, it's more resistant to corrosion from water and the elements generally than a standard car type cigarette lighter plug.
John Deere Tractors apparently have a BMW compatible plug, similar quality, for less.
