If you get reasonably proficient with VBA, you won't have to call IT for these matters. That may be against your company's policy, but I'll leave that ethical dilemma to you. If I wanted to learn VBA, I would study these three books in order
VBA for Excel for Dummies (Walkenbach)
Power Programming for Excel VBA (Walkenbach)
Professional Excel Development (Bullen, Bovey, et al)
Concurrent with that study, you need to start solving real-world problems. Go to social.msdn.microsoft.com and start reading the VBA forums. Answer whatever questions you can. The ones you can't, wait for someone else to answer it then reproduce the problem and solution so you know it. Do the same with stackoverflow questions by following the vba tags. If any question seems too complicated, just skip and go to the next one.
Read Excel VBA blogs http://www.dailydoseofexcel.com/dicks-blogroll/ Start with http://datapigtechnologies.com/blog/ and http://blog.contextures.com/ for sure. They're not just VBA, but they're very well written.
Here's what will happen: In 3-6 months you will have discovered a whole new world. You will have written simple macros for yourself and your coworkers that eliminates some of the drudgery from your day. You'll start looking for wasteful process you can eliminate with simple code. In 6-12 months you will have become reasonably proficient. You won't need IT to fix minor problems for you. You will be the go-to Excel person in your office (learning VBA will make you better at Excel). You will have helped thousands of people here and on the msdn forums all while helping yourself.
After 2 years you'll probably start being recognized by MS and the community as an expert. You'll get sick of answering the same questions over and over on the forums so you'll start a blog and direct people there. You'll have arguments with your husband about whether VBA is a "real" language, but he'll be secretly proud of you for what you've accomplished. After 5 years you'll have co-authored an Excel book, quit your job to be an Excel consultant, and learned C#. YMMV of course.
