How brave are you? ;)
I'll defer to Scott on the internals of ZK and why it
might be necessary to delete the ZK data dirs, but
what happens if you just correct your configuration and
drive on?
If that doesn't work here's something to try
Shut down your Solr instances, then.

My plan would be to do the following, while users are still online (it's a
big [bad] deal if we need to take search offline):
1. Take zk #3 down.
2. Fix zk #3 by deleting the contents of the zk data

Rebuild my *SOLR* collections? That's easy enough for us.
If this is how we're incorrectly configured now:
server #1 = myid#1
server #2 = myid#2
server #3 = myid#2

Good! Hopefully that's your smoking gun.
The port settings are fine, but since you're deploying to separate servers
you don't need different ports in the "server.x=" section. This section of
the docs explains it better:

Hi Scott,
First, we are definitely mis-onfigured for the myid thing. Basically two of
them were identifying as ID #2, and they are the two ZK's claiming to be the
leader. Definitely something to straighten out!
Our 3 lines in zoo.cfg look correct. Except they look like this:

Hi Joe,
Yeah, two leaders is definitely a problem. I'd fix that before wading
through the error logs.
Check out zoo.cfg on each server. You should have three lines at the end
similar to this:
server.1=host1:2181:2281
server.2=host2:2182:2282
server.3=host3:2183:2283

Hi,
We have a simple architecture: 2 SOLR Cloud servers (on servers #1 and #2),
and 3 zookeeper instances (on servers #1, #2, and #3). Things work fine
(although we had a couple of brief unexplained outages), but:
One worrisome thing is that when I status zookeeper on #1 and #2, I get
Mode=Leader
