You'll find some useful information on rooting the Rugby Pro
here, including a link to a
rooting guide.
Once rooted you may be able to uninstall the apps in the usual way (I've not used this phone, which is why I'm saying "may"). Otherwise you can uninstall them using Titanium Backup. Do make sure that nothing critical depends on them - if in doubt, try disabling (or "freezing" them using Titanium) before uninstalling, so that you can easily undo this if it causes problems.
In fact I'd make one addition to the rooting instructions above: once you have ClockworkMod recovery installed, use it to take a backup of your phone
before installing the file which roots the phone. That way if there is any problem you can just restore the backup. I'd personally recommend making a backup using recovery before making any changes to system software, including removing the bloatware that you want rid of, simply because it's the easiest way to fix things if anything goes wrong.
