Should I attempt audioengineering tricks on a multi-fx board for bass?

I'm not an audio engineer by any means. I simply have ADHD and have read some blogs to learn stuff which creates this weird dynamic where I know more than the average musician but don't know enough to really know what I'm doing with this.

I have a Boss GX-100 multi-fx pedal that I use on bass. It's a good pedal with high quality effects, but I'm sure they don't compare to high-quality plugins. I also don't know whether some of the stuff I've been reading even matters in live sound settings.

I've been reading about aliasing, limiting, and saturation recently. The Boss GX-100 has a great compressor that allows me to have full control over parameters and signal blending (or parallel processing). I generally play songs with wide dynamic ranges and, although the tone sometimes requires me to play harder, there are times when that causes some unwanted clipping (or something of the nature). I have some light compression on (2:1 ratio, medium-fast attack and release, and some blended cleans) on my bass for tone. But, I'm wondering if I should add another compressor either in series or parallel for more extreme compression at a higher threshold to avoid unwanted clipping when I really dig in.

I play a Sire P7 (active preamp that I typically leave flat) into the Boss GX-100 (with the compression described above and some mild overdrive), into a TC Electronic BQ500 (MOSFET preamp with light comp). The Boss GX-100 also can work as an interface recording at 24-bit/48khz. I can also have up to 15 effects at once, including multiple of the same type, so using multiple compressors is entirely feasible.

Is this even something I should worry about in a live context? If so, what advice would you have for me using the gear I have? Some more specific questions:

1. Is aliasing only a thing in recording/using a DAW or is it also a thing with digital preamps and power amps?

2. Should I be applying an LPF and/or EQ cutting everything above 20khz to prevent aliasing in live application?

3. Would a high threshold compressor with a high ratio (20:1 or more), and near zero attach/release function as a limiter?

4. In the scenario in 3, would the "limiter" even help anything or would it still clip/distort similarly, but caused by the limiter instead of preamp?

5. Would it make more sense to limit in parallel, before the light compression, or after?

6. Where would you put light noise gates in this signal? Before compression to avoid unwanted signals from being brought up? After to cut down some of the unwanted signals that were brought up? Both?
