I am 99.99 % certain I am not running the UEK kernel but trying to understand the seemingly contradicting information as detailed above.

I welcome any test I can perform to prove empirically whether it is the uek kernel or not.
If I then upgrade yum (required to get the yum changes to support kernel-uek installs) and then upgrade the box to the latest and reboot:
# uname -a Linux localhost.localdomain 2.6.32-100.26.2.el5 #1 SMP Tue Jan 18 20:11:49 EST 2011 x86_64 x86_64 x86_64 GNU/Linux
We're now running the latest UEK Release 1 kernel (2.6.32-400.26.2.el5uek) and it identifies itself as such:
# yum update yum # yum update # reboot
Notice that it now says el5uek in the uname string.
# uname -a Linux localhost.localdomain 2.6.32-400.26.2.el5uek #1 SMP Tue Apr 23 19:04:54 PDT 2013 x86_64 x86_64 x86_64 GNU/Linux

I had no understanding the the UEK kernel updates required a YUM plugin.
Must this be present to patch from kernel-uek-2.6.32-100.26.2.el5.x86_64.rpm to for example the ELSA-2011-2014 that upgrades the kernel to kernel-uek-2.6.32-100.26.2.el5.x86_64.rpm ?I'm not sure what YUM plugin you're referring to, but there is no requirement for any plugins to install to a specific kernel, assuming you have yum properly configured to point to either ULN, public-yum.oracle.com or a local YUM mirror. If so, just run:
# yum install kernel-uek-2.6.32-100.26.2.el5
