There is no easy way to install drivers in Linux. I for one try to avoid it. It could really mess things up especially graphics card drivers. I only use Nvidia supported cards. Do the homework before you purchase your new hardware. The happy news is there are many many hardware that are now supported by the Linux kernel out of the box. I really am surprised when somebody still have to manually install a driver in Linux.
Also if you are planning to add a printer, use HP. It very friendly with Linux.
I have been wondering about the kernel updates a couple of days back. Now it all make sense. The Ubuntu security team just released a post that the second kernel update in two days is a kernel regression.
A kernel regression happens when a later update breaks a previous patch. Happens when you try drive too fast I guess.
