You should un-install WinPcap 3.01-alpha and install WinPcap 3.1 beta.
Earlier versions of WinPcap don't support capturing on PPP interfaces
(such as dial-up modems) very well.

No - you can also use WinDump:
http://windump.polito.it/
(a command-line tool - it's tcpdump, ported to Windows by the people who
did WinPcap), or Analyzer:
http://analyzer.polito.it/
(a GUI-based network analyzer, also from the people who did WinPcap), or
Packetyzer:
http://www.networkchemistry.com/products/packetyzer/
(a Windows GUI-based analyzer whose packet analysis code is that of
Ethereal).
Also, if you've installed Network Monitor, that might also let you
capture traffic (it doesn't use WinPcap).

See the links above for the other tools; for Ethereal see
http://www.ethereal.com/distribution/win32/
for the Windows version.

See above for some other tools that also work with WinPcap.
