If you're using Apache 1.3.x or 2.0.x, mod_jk is pretty simple overall.
No, you don't want to even try in-process stuff and, yes, if you have a
firewall in between Apache and Tomcat that drops idle connections you
should read carefully (this is covered by the docs).
The only big complaint I have is that the mod_jk docs don't make it
terribly clear (or didn't last I checked) exactly how to set jvmRoute in
Tomcat and how extraordinarily critical this is when doing load
balancing. The Tomcat docs don't make this terribly clear either --
apart from a comment in server.xml. Most everyone I know who tries
mod_jk load balancing gets hung up on this one point unless/until I give
them a detailed explanation. Apart from the lack of clear/obvious
information on this in the mod_jk docs (which should include it
considering most folk won't think to check both mod_jk and Tomcat docs),
this is actually very simple as well, though.
I am looking forward to mod_proxy_ajp as it is supposed be a tiny bit
faster.

mod_proxy_ajp? Yet another twist. Its just hard for me to believe that
"how do I integrate tomcat and apache httpd?" is such a mystery /
unknown. This seems like it would be question #1 on any Tomcat FAQ.
So where can I found out more about mod_proxy_ajp. Is there a Tomcat
resource which explains the configuration of it?

After wasting time trying to configure mod_jk, I thought I'd just
wipe my mind free and just play dumb for a moment. If Apache can
proxy requests using mod_proxy, what is the benefit of using mod_jk
as an integration technique between httpd and tomcat, if integration
is *not* in-process, which I understand is not recommended for
Tomcat 5.5?
Actually, in-process with mod_jk is only supported (and, I use the
term lightly :) for TC 3.3.x. For any higher versions it doesn't
work at all.
You've managed to grasp the deep, dark plan of the Tomcat
developers: It is expected that people will migrate to mod_proxy_ajp
with Httpd 2.2+, and mod_jk is expected to move to supporting
IIS/SunOne only (and, the later only if somebody steps up with
interest :).
