OS X keeps appending "(2)" to computer name

Try exporting the base station configuration to your Desktop. Open it and see if your computer name is listed more then once in the configuration file. If it is see if the MAC address is different for both. If it is delete the entry, in the configuration file, that does not match the MAC address of your WiFi card that is shown in the System a Profile. Save the file and re-import it back to the base station.
The times that I have seen the rename issue is when the Airport base station thinks the same computer name with different MAC addresses is on the network at the same time. I have cause this to happen when I plugged my computer into the Ethernet and changed the selection order from WiFi being highest to Ethernet being the highest.

Okay, so how do I go about exporting this? I find nothing in the Air Port Utility that seems to offer an export function.
It is up in the File menu, but will be greyed out until you select "Edit" for the device in Airport Utility.
Got it, thanks.
Okay, I used TextEdit to look at the file. My computer name isn't even listed once! Any further advice?

If I configure Energy Saver to "prevent computer from sleeping automatically..."(and uncheck all other menu items) — and instead manually use the Sleep command from the Apple menu, the Name (#) stops.
I haven't tried enabling the other Energy Saver items yet.

Use it to check health, size, mount or unmount. That kind of thing
Seriously... I've found this first answer to be most correct though all the betas and releases. I have Apple Airport both 5GHz and 2.4GHz in multiple locations. I've restarted everything, but the only consistent fix is turning off "Wake on network access". Which is no great loss really, never worked over WAN anyway which is where I really need it.

WAN is probably the most ridiculous failure from Apple. It has not worked reliably since 10.6. Yosemite? Forget it. Might as well leave everything on and waste electric, while Apple is busy making itself look golden with their PR Environmental announcements.
revert to mDNSResponder
some people seem to be having less trouble with these annoying naming conflicts (and other name-related issues) by reverting to mDNSResponder, the old pre-Yosemite service that handled this stuff.
see http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-you-can-do-to-fix-it
i just wish that Apple's bug tracker weren't such a heaping pile of **** that end users could actually hope to get issues like this fixed.

Just saw this on twitter, so help may be on the way:

After many complaints from the developer community about poor networking performance on Yosemite, the latest beta of OS X 10.10.4 has dropped the discoveryd in favor of the old process used by previous versions of Mac operating system. This should address many of the network stability issues introduced with Yosemite and its new networking stack.
The discoveryd process has been subject to much criticism in recent months as it causes users to regularly drop WiFi access and causes network shares to list many times over, due to bugs. Many developers, such as Craig Hockenberry, have complained about the buggy software and workarounds have been found to include substituting the older system (called mDNSResponder) back into Yosemite.
discoveryd would cause random crashes, duplicate names on the network and many other WiFi-relate bugs. In the latest beta, Apple appears to have applied the same fix as the enthusiasts by axing discoveryd completely.
Looking at Activity Monitor on OS X 10.10 seed 4, discoveryd is no longer loaded by the system — instead relying on mDNSResponder. The ‘new’ process is really the one Apple used to use pre-Yosemite and did not have these problems.
It is still unclear why the change in the networking stack was ever made given that the old process worked so well and the new process had so many issues. There has been some speculation that the new stack is related to AirDrop and Handoff functionality although testing showed that these features still worked when the system was reverted back to the old process.
Regardless, it will please many to see that Apple has finally addressed these complaints, even if it embarrassingly involves going back to the old system rather than fixing the new code. OS X 10.10.4 will be released to the public in the coming months.
Apple is focusing on performance and stability for iOS 9 and OS X 10.11, so it will be interesting to see whether discoveryd makes a comeback in Apple’s next-generation operating system.
Seems to me all my issues with renaming are over. Not a problem since this update. What are others experiencing?
So are you saying those facilities don't work or are they causing you to get naming errors? hostname (2)
Still causing other users naming duplication or (2) (3). Seed people have posted this information. This update looks to be a quick patch. It's not completely fixed.
