You are not a code monkey. You have read TOACP thrice. You love programming in Python. You love networking/sysadmin/build and release stuff. If all the above is true, there is really no value in doing Red hat, cisco or juniper certification. If you love programming, contribute to open source. People will notice you when you work on open source projects. Then by the time you finish college, you might get some consulting work as a freelancer. Once you are get some money doing consulting, try to do some simple paid webapps. You would also be familiar with what people want by that time.
