  For the pager - no, not that I know of. That is indeed intended behavior and
a general feature of many of the apps that make up the taskbar (kicker panel).

  The same applies to the applications shown in the taskbar. When you scroll
the mouse-wheel over that portion of the taskbar, it will cycle through the
open applications. (the same applies to the 'tabs' area on konsole when
multiple tabs are open.

  For the pager and taskbar, one way around the issue (and a way to increase
the screen real-estate) is to 'autohide' the taskbar. That way it is out of
the way and there is no possibility of accidental scrolling.

(personally I enable the mouse-well over desktop background intentionally.
Most people do not make use of multiple desktops just do to the additional
task of switching between them. If you always leave a tiny bit of background
showing on each desktop (say in the top-left or top-right corner -- you can
always scroll there to switch between desktops :)

Another tip in that regard is to set global shortcuts to allow moving a window
to the previous or next desktop -- since the Win key isn't used -- it is a
perfect candidate. A couple of really handy key combinations to set are:

Switch to Next Desktop=Win+Right
Switch to Previous Desktop=Win+Left
Window to Next Desktop=Win+Alt+Right
Window to Previous Desktop=Win+Alt+Left

Walk Through Desktops (Reverse)=Win+Shift+Tab

Maximize/Minimize
Window Maximize=Win+Shift+Up
Window Maximize Horizontal=Win+Alt+Up
Window Maximize Vertical=Win+Up
Window Minimize=Win+Alt+Down

Since the Win key and Alt key are generally next to one another under the left
hand, that makes that combination ergonomically friendly as well...
