Hey Chris, welcome!
From what I've seen, Skip is correct in that a lot of people on these forums are IT guys. Myself, I'm a systems engineer for a software company. I was in a similar position to you two years ago. If you want to chase, I'd recommend going out as a chaser first, and an IT guy second. Nothing is stopping you from chasing yourself, but there are some hurdles to being the IT guy for a research team.
I won't try to speak for everyone, but it seems that a laptop and a GPS unit are all that many chasers are bringing out into the field. How often does a laptop break to the point where a reboot won't fix it? Even then, what's the loss in missing one chase day? For guys with research grants - it's a lot. For the majority of chasers - it's probably not much. The guys lugging around a ton of equipment like Josh Wurman seem to be the exception rather than the rule.
Try attending some storm chaser meetings, Skywarn training, and talking to people here to make some connections. There may be a few chasers that value the cost-sharing more than experience in a partner. Heck, I found out that my wedding photographer is a Stormtrack member. Nothing beats wedding jitters like talking severe weather
It sounds like you want to learn some meteorology, and it's a good idea if you want to go chasing. Lurk/search on the forums here, and ask questions when you don't see an answer anywhere. The sticky in this forum has links to a lot of great resources, but I'll point out of a few of my favorites:
http://spc.noaa.gov (outlooks, analysis, and plots that you can draw your own analysis on)
http://www.ral.ucar.edu/weather/model/ (model forecasts)
http://www.theweatherprediction.com/habyhints/ (Wikipedia-level information on tons of weather topics)
GrLevel3 for a laptop, Radarscope for an iPhone (level 3 NEXRAD radar apps)
Storm Chasing Handbook by Tim Vasquez
Storm Structure 101 DVD by Mike Hollingshead
Mike's DVD is great because at a certain point it's easy enough to look at various plots, radar, satellite, etc. and have an idea of what's going on in the atmosphere. This DVD sheds some light what's going on in the sky around you during a chase or a bust. It's not a replacement for real experience, but it's a darn good intro course.
