Really it's best to use whatever you are most comfortable with, and what you can bear to carry all day. Your list sounds well rounded, I use a similar setup, with a 50, 28 or 24, and if I go wide I use a 19-35 zoom or the 14mm. These are best for street (the ultra wide less so). The 1.4 should be fine but I always find the the most interesting stuff happens at night so I've setup for the slightly faster set of nikkors. The longer 105 can be handy and depending where your trip might take you the length could be useful at events or shows.
