You can remove "qlikview" from the url -- or assign another path -- as discussed in this thread.
The AP files are in Program Files\Qlikview\Web (for QV10). You can change the AP logo in one of two ways.
1. Replace the AccessPoint.jpg file with your own log, using the same name.
2. Modify img tag in index.htm to point to your own logo.
img src="AccessPoint.jpg" <=== change to your file.
