It's hard for me to say for certain since I don't have your model of phone, and I'm not sure what you mean by "in there". If by "in there" you mean as "Phone-only contacts", I would say definitely delete them (after you do a backup for safety). If by "in there" you mean that your contacts are now "Google contacts" are now synchronized with the Gmail servers, then I guess you could choose to simply stop syncing contacts and calendar for that Gmail account.
But overall, I guess I would recommend that you start with a clean slate by doing the following:
1) Make sure you have a copy of your contacts and calendar backed up for safety.
2) Turn off the HTC sync so that you don't accidentally delete everything in Outlook.
3) And then, delete the contacts and calendar information so that you can start with a clean slate. (Eliminating duplicate contacts is torture.)
(You probably already know how to backup your Outlook stuff-- and the instructions for doing so vary with the version of Outlook-- but if you're not sure how to do it, you can look up how to "export a PST file".)
