I do appreciate all the information here, but I do have to say I am a bit surprised. I was expecting more people to talk about having used Scientific Linux with what the website for it said, especially considering it was put together by Fermilab and CERN. Anyway, like I already said in direct responses to feedback above, I am taking everything you all say into consideration, and am not rushing into anything at this point. In about 3 more weeks, I will have a lot more time to try and toy with all of this, so I appreciate all the feedback to let me make a well-informed decision.
I've never used Scientific Linux myself, but having looked at this distro, I have to say it's just a free version of Red Hat Enterprise Linux. I'd expect that something calling itself "Scientific" Linux would have some (in fact, many) built-in open source scientific and mathematical tools but it doesn't appear to have this advantage. So, unless someone is actually working in one of those labs where the default OS is SL, why would they go out of their way to install it?

I wish I had more free time as well. Between a family (including a 3 week old newborn), having to work part-time, and having to go to college full-time (so I graduate before I'm 46), I have to be very efficient with my time. That is why I'm just trying to find out what would be beneficial to learn and what would be a waste of time that I will never use. Seems like I already got the answer to that though, which is to gain a solid understanding of using command line interface.
I really appreciate everyone's feedback here. You all really help me to save a lot of time and frustration. Hopefully as I learn more, I'll be able to do the same for others here in the forums down the road.
Yes, time is important. Learning to become a power/advanced user of Linux doesn't mean you have to suffer from the outset. I'd recommend Ubuntu as a very good starting point. It's designed for ease of use. Contrary to what someone posted, it is NOT meant to be a Windows clone (that dubious honour belongs to some other distros, including the short-lived Lindows). Rather, it's based on Debian, which is characterised by the apt package management system. This basically means that software installation is usually (not always) a doddle. Package management is not unique to Ubuntu/Debian, other distros like Redhat (and Mandrake/Mandriva) have had "RPM" (RedHat Package Manager). Even an "advanced" distro like Gentoo has the Portage system based on ebuild and emerge (as does Arch with pacman). Basically, all these package management systems help to make your life a little easier because they resolve software dependencies when you try to install something new in your system.
If you don't wish to use one of these package management systems and decide to do all your installs from source, then:
a) you won't really learn anything new other than commands like tar -zxvf whatver.tgz, ./configure, make, make install. After a couple of times, it becomes completely rote - when it works as it should, that is.
b) and when it *doesn't* work as it should, you will be wasting most of your day(s) [yes, it can be in the plural] wading through dependency hell, reading support documentation, trying (and failing) to locate compatible libraries, and desperately trawling through and finally, working up the nerve to actually post your query on a linux forum. In the old days, they'd have derided your noobishness, told you to RTFM, cast aspersions on your intelligence and told you to go back to "Wind0ze, yo!". But now, at least, they tend to be more helpful - the hardcore "l337 g33ks, y0!" have become more subdued. So you can expect some meaningful help online.
Anyway, I strongly advise you to go with a more noob-friendly distro, and Ubuntu is the most popular choice. You can, of course, delve deep into the guts of Linux using this distro, because you still have access to a command line interface. And if you really insist (or packages for that software are lacking), you can still install things from source.
Good luck!
