Went snooping in my BIOS. There are a few options I am not too familiar with and, am not real sure how they should be set. Any advice would be appreciated.
SATA Power Management  -  Enable or Disable?
PCI SERR# Generation  - Enable or Disable?
NIC PXE Option ROM Download  -  Enable or Disable?
As of now, all of these options are Enabled.

SATA Power Management.  Normally, I would say disable this. It could affect a SATA device coming back from standby.  If you don't use standby then I would also say disable it. 
PCI SERR# Generation, can't find much about this other than it has something to do with PCIe.  I don't have this in my ASUS Z170 motherboard.
NIC OXE Option ROM Download, unless you are set to download BIOS updates directly, from what I find that should be disabled. 
 
What motherboard do you have?  I don't have any of these options (at least by those terms) on my current Z170 motherboard and don't recall them on my older Z77 motherboard.

I'm thinking that your Windows power and performance settings are probably more relevant to audio applications than the BIOS settings.
 
As a rule I generally disable any unused onboard devices in the BIOS such as ethernet network adapters, onboard audio, etc., so they are not detected by Windows.  If Windows sees them it will load a driver and enable them.  I do this to minimize unnecessary resource usage.
 
As for the rest of the BIOS, I usually take most of the defaults.  Anything related to overclocking gets skipped.  I usually disable anything related to fast boot (using normal boot).
 
As long as the devices you need are detected and the system can boot without errors, the Windows OS is pretty much plug and play with the hardware.  There are many discussions available for optimizing Windows for audio applications.

There are CPU related settings in the BIOS that can have a significant affect on performance.

Yup, but the defaults should work a-ok in most cases.  Laptops might be more sensitive to this, but I was generally referring to desktop BIOS.
 
If you don't know what you are doing and fail to RTFM, then you are better off with the defaults.

True... and (unfortunately) why many off-the-shelf machines don't expose parameters in the BIOS.

This is the first machine I've ever had that has such a pared down BIOS. I am accustomed to seeing a lot more parameters that are each very clearly stated as to what they are. It's an HP machine with a Joshua-H61-uATX motherboard.

I have an Asus motherboard with the same chipset, H61 (3rd gen Intel Ivy Bridge), with their advanced UEFI BIOS.
 
Asus documentation is very good, and the BIOS seems open, nothing obvious hidden away.
 
But in the case of HP boards, your best bet is probably to visit their community and see what you can learn there.

PCI SERR# Generation  - Enable or Disable?

My interpretation (I can be wrong): if your have broken hardware but still want your system to work, "Disable" can help. With healthy system, Enable is fine.

Do you mean NIC PXE ? Then:

In short, "Disable" is the right choice (till your system has no local disks and boots from the network, which I guess is not the case). Nothing is wrong with "enable", it just takes some time to load and if PXE booting get priority over local disk in the booting order, your computer will try to find the server to boot from every time you turn it on...
That is not an interpretation, I use PXE a lot (good for new computer installations, thin clients and diskless farms, once your have properly configured DHCP+TFTP server  )
