Help getting most out of RT-N66U

I'd like some help tweaking my Asus RT-N66U.

I'm using the default firmware presently, and have both a 2.4GHz and a 5Ghz network. Both are set up similarly.

Here's how I have it set up:

(I turned off the router's radio briefly and took a screenshot)

I have roommates and thus can't spend hours testing different configurations. We live in a small apartment and it's not so much an issue getting signal to all of the computers, but I like to sit out by the pool with my dog and use WiFi on a tablet/laptop, and it's currently at the very edge of the range. We have a very sharp drop in WiFi signal through the outside walls of the building, which are brick and very thick.

Even though 2.4GHz is very busy around here, and 5GHz has absolutely no networks, I still get more range on 2.4GHz on channel 5 (which came out on top in the little bit of testing I've been able to get away with). I have my desktop wired, but basically everything else in the house runs on WiFi - 4 computers, 4 consoles, 4 phones. 5GHz makes it throughout the apartment pretty well.

My questions:

Will I likely see an appreciable range boost by dropping to 20MHz only? Will I realistically lose any throughput on my 2.4GHz network by doing this?

Will moving as many devices onto the 5GHz network as possible improve my 2.4GHz range?

Is running a 5GHz network at the same time going to reduce my signal strength on 2.4GHz? Is having a guest network on either going to harm my signal strength? I currently have a guest 5GHz network.

Is WPA + AES fine/optimal? I have options for WPA2, personal and enterprise, and TKIP. Our neighbors are mostly (all?) rednecks and I don't have any really sensitive files shared, I'm more thinking about it from the angle of reducing overhead on the network.

Am I probably best served leaving the transmission power at the default setting of 80mW? I have a vague understanding of SNR, more power can be counterproductive, but I can't easily sit out by the pool and play with the power output. I'm not sure how best to even test it - should I be doing LAN file transfers and timing them?

Are there any other settings you would change? I currently have all of the optional features I'm not using disabled, including WPS.

Thanks in advance!

Thanks. Read through it.

I'm not sure which of my questions can really be answered by others, and which I have to answer myself. I was able to formulate most of these questions only after spending several hours on Google looking reading on the topics - msot of the questions that remain are ones I was unable to find existing answers to, sometimes because they are specific to my hardware. The RT-N66U seems a pretty common router among enthusiasts though.

EDITED
