No. Hostapd implements the AP side, wpa_supplicant implements the 
station side.

Your choice. You can implement a bridging AP or a routing AP. I've gone 
for routing.

If your distribution has a hostapd package then that typically comes 
with infrastructure to accomplish this. In my case I edit the hostapd 
configuration and when I'm ready I restart the daemon using the 
/etc/init.d/hostapd script (Debian-based distribution).

I don't use wpa_supplicant as all of my clients are Windows-based. But I 
understand that Network Manager may be what you're after. I suggest
