The best way to plan traveling on the CTA is to use the Google Transit feature in
Google Maps
The CTA is one of the many public transit agencies all over the world that participates in Google Transit

This is what I use when I'm in the city and it's never been less than perfect.
The CTA also has a trip planner feature on their website that uses Google Transit for results

Here's a direct link to

Or

Use the drop down menus to choose your departure dates and times
Click on Get Directions
You'll, more than likely, receive multiple suggested routes.
Click on any one of the routes and scroll down to see the details of the route.
Buy or reload your CTA Transit Card at one of the machines inside the Metra Station inside CUS
After you leave your train, head towards the Great Hall, the Metra station is on the right before you go through the glass doors - CTA Transit Pass machines are on the right as you walk inside.
It seems that a lot of people with long layovers tend to stay in the, imho, hideously, ugly area around CUS.
There's absolutely no reason not to see a little of the city without any fear of missing your train.
For a cheap fun mini tour of the city, taking a round trip on the 151 bus that originates and terminates in front of CUS is a fun idea, you can even haul your bags onto the bus if you don't want to rent a locker.
Using public transportation in Chicago is fast, easy, reliable, and safe.
Also, as a native and former longtime resident, I can tell you this:
It's always been the 'L' and it's NEVER Chi-Town unless you want to mark yourself as a tourist, suburbanite, transplant, gangsta, or Guy Fieri wannabe
Speaking of the L, one of my favorite sights ever (back in the day) was on the Belmont and Sheffield platform.
