If you're talking about 50mbit or less combined (which I see you are), you may find something like a Cisco Linksys RV042, or a Peplink Balance or Cradlepoint MBR unit, quite satisfactory. As long as your connectivity comes in over Ethernet (whether it's bridged from ADSL or just plain old metro Ethernet), you should be fine.
One problem with this ...

If I wanted to connect two offices, that are 500ft apart, I'd use Fibre. Couple of decent HP or Cisco switches at either end, Fibre 1Gbit GBICs, job's a good-un. Instead of trying to do it in a single stretch of copper, with some switch in a broom cupboard.
Ask yourself this, how much do you get paid? Figure out how much this "solution" is costing you, ...

The booster switch need not be L3-capable to work with an EtherChannel bundle, but it does need to be a managed device and support the same protocols (LACP or PAgP) as the other switches on the ends. Just configure one bundle going up, and one going down. Ensure that the booster switch's VLAN database and trunk allowed vlans match the ends, and you should be ...

This is a manufacturing tolerance. It's not configurable or adjustable.

Given the actual watts involved - by definition, negative dBm is < 1mW - the implementation details are probably not important to any problem you're trying to solve in a real-world scenario (unless you're installing tens of thousands of these in a hypersensitive environment).
Edit:
According to this Cisco forums thread this is not configurable via ...

are you sure you tested it thoroughly?
according to this:
arp_ip_target specifies the IP addresses to use as ARP monitoring
peers whenarp_interval is > 0. Multiple IP addresses must be
separated by a comma.
i have mode=1 setup on couple of servers [although with single ip provided] and it runs just fine, even without any traffic flowing. ...

To add to what's been said for data, it won't matter at all for POE since the voltage is applied across the pairs, not within them (1-2 and 3-6 for Alternative A, 3-4 and 7-8 for Alternative B).

if the reverse is on both ends then there is no problem.
for 100BASE and less, reversing pair polarity on one end will probably not work. however, I have seen chipsets that are tolerant of these wiring errors. I think this has become more common since the introduction of Gigabit Ethernet.
for 1000BASE and 10 gig, pair polarity doesn't matter. some ...

As long as it's reversed on BOTH ends then I can't imagine it would matter at all. Of course, if someone one-day re-terminates one end correctly then you're likely to have issues.
Depending on which pair it is (you didn't mention), for 100BASE there's a 50% chance that it won't matter since only 2 pairs are used; 1+2 (Orange) and 3+6 (Green).
For the sake ...

Ethertype doesn't encode payload length, but the type of the payload packet in modern networks.
Originally, the field on that position could contain the payload length, naturally encoded in bytes, not bits (why on earth should you use bits as a unit here?).

While I'm not allowed to make direct product reccomendations, I will say this:
Avoid anything made by Asus (Linksys, Belkin, or anything you'd get from PC World, BestBuy or Walmart).
It's not designed for the Business/SMB/SME/Enterprise.
Access Point manufacturers (for the entire wireless network) I'd trust are:
HP Procurve MSM (especially with an ...

don't use a repeater. Install a second identical AP (same ssids, same encryption. Probably different channels).
Connect them to the same LAN and you are done. Clients will automatically connect to the one with the best signal.

I realize you're looking for a GUI way to do this but you can get the MAC Address from the command line like so:
$ ifconfig em0
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=b<RXCSUM,TXCSUM,VLAN_MTU>
inet6 fe80::20c:29ff:fefd:f61d%em0 prefixlen 64 scopeid 0x1
inet 198.18.152.169 netmask ...

For large networks, you need to setup some hierarchy like in the following image.
It becomes impractical to have large number of computers in the same L2 domain. You need to use subnets, VLANs, routers and/or higher layer switches. One clear disadvantage of having too many computers is the same subnet is the increase of broadcast traffic (same broadcast ...

You can set up virtual interfaces by appending to the physical interface name :<n> where n is a number.
$ ifconfig eth0:0 192.168.1.1 netmask 255.255.255.0
Using the ip utility, you can even specify a name:
$ ip link add link eth0 name virt1
$ ip addr add 192.168.1.1/24 dev virt1
