This is a great question as the technology industry and advanced computing skills are becoming expected skill-sets for many job seekers. There are several options available to you for building your IT skills provided you've identified some of the core programs and applications with which you need to be familiar.
First and foremost, use the people and resources at your current job. There is nothing wrong with asking your colleagues to sit down and teach you how to use these programs at a higher level. Also, depending on your company size, they may already have internal courses you can take, or be willing to sponsor certification courses from a local university or college.
Second, check out local computer and tech stores. They will have listings of certification courses, or perhaps even provide them.
Third, look at adult-learning classes either at on-line or community educational institutions. These classes are often at night and for short-stints of time so it won't be like getting another degree.
Finally, look into on-line web communities such as EdX or Lynda where a wide variety of courses (from IT to gardening) can be found.
I hope this helps as begin planning for your next steps. Best of luck!
