Here's a bunch of resources for ya.
Start by checking out OpenTopography. They have data for free download as well as a great tools page:
https://opentopography.org/
​
For free software I recommend checking out:
Cloud Compare https://www.danielgm.net/cc/
QTReader http://appliedimagery.com/download/qtreader-64-bit/
and Fusion http://forsys.cfr.washington.edu/FUSION/fusion_overview.html
​
Also free for small datasets is Lastools. The creator, Martin Isenburg has an excellent blog as well.

If you know python or R there are some great packages:
laspy https://laspy.readthedocs.io/en/latest/
lidR https://github.com/Jean-Romain/lidR
​
For educational resources:
I've taken some good courses online with Penn State World Campus. I haven't taken their lidar one, but it looks pretty good.

There are lots of resources out there you don't have to pay for, and colleges are always a bit behind the industry. I see more programs popping up these days that teach not just GIS but focus more on remote sensing and geodesy. I would look for something with that kind of focus rather than your standard GIS program. Honestly, you can learn a lot about the work if you try out some mapping using a drone with a camera and then create a point cloud using structure from motion (aka phodar). Software like Pix4D, Agisoft Photoscan have free trials I think.
For lidar textbooks I recommend the one by Shan and Toth:
https://www.amazon.com/Topographic-Laser-Ranging-Scanning-Principles-ebook/dp/B009NZVX2W
Also, it's always a good idea to read up on and understand accuracy standards and file formats at some point:

For drone based lidar, the company to pay attention to these days is Phoenix LiDAR.

Hopefully gives you some of what you're looking for. Best of luck!
