I also have a Tetra 9 watt UV clarifier. Does that affect the bioload needed for the skimmer? If so, how much?

I don't think the UV has any impact on non-living material (e.g. dissolved proteins).
UV sterilizers work by irradiating the DNA of micro organisms in the water that passes through the chamber, making the DNA non-functional in cell replication. It doesn't kill the organism instantaneously, but instead, renders it useless in reproduction to interrupt the life cycle. UV effectiveness depends on the wattage and contact time for irradiation. Additionally, if much of the water is able to bypass the UV flow circuit, a significant proportion of competent microbial population remain in the system to replicate.

A UV sterilizer doesn't affect bioload. UV sterilizers generally will only kill algae in the water column, bt are advertised to control Ich. Most Uv sterilizers aren't even close to powerful enough to kill Ich.
Generally, you have to spend more money on an HOB skimmer to get good results than you would for an in-sump skimmer. An in-sump skimmer also comes with the cost of a return pump and plumbing too though. On a small tank, say less than 50 gallons, an HOB is a reasonable choice. Bigger tanks tend to function better with an in-sump skimmer.

+1 The Deltec MCE 600 is the largest you can get in HOB that i know of. I owned one for years and its still very quiet and pulls air as advertized. One thing is though you will need to keep air intake clean. The best way to do it is disconnect the pump each time you clean the cup. this way air line will soak and purge itself.

Reef octo does make a nice hob skimmer but one of the biggest selling points for me on the deltec was the overflow line. Off the collection cup it has a return line that plumbs back in to feed chamber so it won't end up all over the floor
