2. If you change the password for the router config, yes, they can reset their router to factory settings and enter a new one. The idea here is to be SILENT - changing things is going to raise flags. Your best bet is to spoof your MAC address, and change your machine name to something appropriate. Nothing which will give you away, and nothing they'll think is unordinary should they decide to check to see who's connected to the AP (assuming they're not tech-savvy).
3. As far as I'm aware, you won't be able to "see" a computer's username and password just by connecting to the AP. Imagine how insecure networks would be if that was the case! If you're looking to gain remote access to a computer, it's likely that you'll have to look for exploits on your target machine and take advantage of them. Read my Guide to Port Scanning with NMAP and my Introduction to Metasploit for some pointers.
In regards to getting local computer passwords, occasionally you see network shares configured so badly that you are able to access the system32 folder. The passwords are all located in the SAM file. You could use OphCrack to crack them.
