honestly, if you're looking at a support role (troubleshooting and config) a degree isn't going to help as often as a cert and experience. You don't need much experience for the typical call center, which is a good way to get your foot in the door so to speak. A+ takes you only a tiny bit further, but it's an important step. Then it's time to decide what direction you want to go.
Personally, I'm fond of the CompTia certs, as they don't technically expire and don't specifically state what they are for (MCP you are likely to be asked specifically what for) so once you're A+, Network+, etc etc, you are technically that for life. Once you've gotten all of those that you want out of the way, then you can look at some beefier certs. If you're interested in networking, Cisco certs. (at this point, going to school for a BS would be beneficial)
