I'd stay away from them for the time being because the technology was rushed
out and is not perfected. In new homes that are specifically wired for
arc-fault breakers they are ideal. But in older homes, light switches were
commonly wired on the outlet circuits. A switch can internally arc when
turning it off while under a load. This arc is enough to keep causing
nuisance tripping. Also, if you're the type to unplug something while it's
still on, the arc at the plug can also trip the breaker.
An arc-fault breaker can be used to power a GFI outlet. Keep in mind that if
you have a 3-wire circuit (2 hots, 1 neutral) such as with 12-3 or 14-3
homeruns to the panel, then you need a special arc-fault breaker that is
identified for common neutral use.

AFCIs are getting better
I would buy a couple and see how it goes. My guess that if you don't
have any multiwire (common neutral) circuits you will be OK on most of
them. If you do get tripping, try it on another circuit and
investigate when you get the bad ones isolated.
One thing to think of is a grounded neutral past the AFCI will trip
One of the biggest causes of nuisance tripping is a ceiling box with
that big kludge of white wires jammed in a wire nut. If you get a
short to ground a regular breaker will not care but a GFCI or AFCI
will trip. If you have a fan in there, it might not actually short
until the fan is running, vibrating the box and you assume you have a
bad fan. If you are careful replacing it and eliminate the short, you
are sure the fan caused it ;-)
That is one of the few places I would tape up a wirenut.
Bad no, but it sure pisses off the next electrician that has to access the
spice. There's nothing worse than getting that sticky gummy tape adhesive
all over your fingers, then your tools, then the switch, then the wall, etc.
If a splice is made proper to begin with, the wirenut should do the job of
holding the splice together and keeping it insulated.
