Sophos installs in about 2 mintues, depending on the speed of your computer. Uninstallation is under 30 seconds.
Scanning your entire computer (an on-demand scan) depends on the size of your hard disk and the kinds of files you have. For a first scan, I'd say 2.5 hours is about normal, but some people have scans of 5+ hours -- probably best to have automatic updates disabled during your first scan.
However, the main strength of AV software is not on-demand scans, but the on-access scanning -- it will check to see if a file is malicious when it is opened for reading/writing.
The third party things you have are regular software -- they function just fine alongside Sophos.
