Updates available, what do they do?

I would not avoid kernel updates per se. Fedora evolves fast and if you 
do this consistently you can quickly find your self out of date and in 
more trouble.

Also note, as another has pointed out multiple kernels can co-exist side 
by side. Installing a new kernel will *not* remove your currently 
running (and presumably working) kernel.

Also, as long as you have added the kernel boot options you need to 
/etc/grub.conf, these options should be copied to the new kernel boot 
options by default.

I would

1. Get all updates, including new kernel
2. Check that the new kernel is in /etc/grub.conf, with the correct options.
3. Reboot to try out the new kernel.

All going well (and much more often than not it does) the new kernel 
will work just fine. If not, you can simply choose the old kernel at the 
grub boot menu and boot to that.
