They will also work in stop-down mode, which can be a bit of a hassle.
Also, practically all of them will become telephoto lenses...

In value-for-money it's hard to beat, but personally I would recommend
you get the two-zoom kit and forget about the OM lenses...it's probably
not worth it. (except maybe if you have a nice 180mm f/2 or a 300mm or
so.)

It works fine.  The adapter is the MF-1 which costs about $100.  You
can also get cheaper
Chinese knock-offs but I can't say how they work.  You can use any OM
lens on
the digital with the adapter, however, focus points can be slightly
shifted, for instance, the
infinity focus point of a 100-200mm is slightly different.  Shutter
speed priority does not
work (from what I've seen with my E-1) but P, A and M do work.
Experiment and bracket.
Here is what the adapter looks like:

One benefit of using lenses (OM Zuiko) designed for 35mm film is the
size of
their image circle.  Generally, this mean zero or little vignetting on
a sensor
2x smaller.

But, one important things is that you can buy things like the 50mm f1.4
for low-light
shooting because there is nothing available like it in Olympus digital
stocks.

You should investigate 'WHAT, if anything...' can be done better with
the Olympus adapter for OM-to-E500 than mounting the same lens on any
other camera.  I use my OM lenses with my Canon 20D with an aftermarket
adapter.  Of course, it is manual focus manual diaphram.  But I love to
use them in low light, because I have all fast prime lenses (fastest
f/1.4 slowest f/2.8) or special lenses (24mm Perspective Correction)
from my OM system.  For available light the lenses will be used near
wide open anyway, so auto diaphram is no big thing (and I grew up in
the days that preset lenses were not uncommon like now).  I grew up
with manual focus and the 20D comes with a screen that is not terrible
for manual focus.

    I have an E-300 and a couple OM lenses I use with the adapter.  If
you're used to using them purely manually you should be pretty happy.
"Manual" focus on the native 4/3 lenses (really, fly-by-wire focus) is
kind of a pain, because it's slow and not very precise, but it's a joy
on lenses which were actually designed for manual focus.  A couple
points to be aware of are
a) the 2x effective focal length factor - on the downside, it means that
all your wideangles become normal lenses; on the upside, it means that
cheap and light 1000mm lenses are now within your reach!
b) it's fairly demanding on the lenses; pictures taken with mine are a
hair softer than I'd like.
