Hello -

In regards to Hz and kHz, what are the numbers that typically fall into the:

- Bass
- Mids
- Highs

Also, can anybody recommend links/websites that reference this?

There is no official definition. Depends on who you ask and what the context is. I personally would say that anything below 100~200Hz is "bass" and anything above 6~8KHz is "highs". Look at the frequency ranges of mixers with 3-band EQ controls.

Google returned "about 688,000 results (0.17 seconds)" for: bass midrange high. Probably enough to keep you reading until the end of the year. You might want to narrow it down with some more directed context.
