2 ways.
You can flash a Rom that doesn't have them
Or
Download titanium backup and delete them through there.
Be warned though, if you delete apps your system needs you will screw up your phone. I recommend buying the pro version of titanium backup and freezing the apps first to make sure they don't have any bad effects, then delete them after a few days.
Make sure you have a nandroid backup of your phone before you delete anything to just in case, so you can go back.
