This is normal and you want it to prevent rocker panel rot years down the road. Manufacturers who care for the longevity of their vehicles do things like this.
I broke one of those off as well but was able to super glue it back on. It seemed brittle. You can take the kick panel off in the footwell and may be able to retrieve it. Or just don't worry about it.
Only the front channel at the head unit carries audio to the JBL amplifier, where the magic happens. The subwoofer is tied into the front channel at the JBL amp so keep the fading centered or forward.
The beat sonic devices are line drivers and only boost gain before it hits the JBL amp, saving...
Soundskins has a product for under the hood, although this is probably way too much material, and the added weight may be an issue for those with hydraulic hood struts...
Yea sounds like a harness would be a good option then to ensure the laptop charging can keep up with the demand.
I can't speak for long term safety of overriding Toyotas engineering, but up to 400watts isn't much power load to add on 24/7 and the circuit is already designed to support it in park.
I don't think you would need over 100w for a laptop unless it was a gaming one, you can check the wattage of the laptop power brick to be sure. If you planned on having more things plugged in while driving then yes the anytime kit would be beneficial.

In this case go with the 8". It should move more air than the 6x9 and circular speakers usually produce a more accurate sound than the oval equivalent models.. Just be sure to get a good mounting plate to cover the gaps. It sounds like you have those skills already.
Try getting the woofers off ebay seperately? If you didn't toss the boxes for the dash speakers, return them and do it the right way.
You really don't want 2 or three way speakers in the doors when you have dash speakers.
Its a safety feature, not sure the trigger but I think the hatch position loses memory somehow and that is the only way to reset the memory. Maybe leaving the hatch open too long after tuning the car off.
