I'm thinking of taking this picture and getting it printed poster size
and having it framed, and hanging it in my room. What do you think of
this idea? If I choose to do it, what kind of resolution do most
printing shops like to see this kind of thing in? I'd have to render it
with some higher quality settings as well.

This is no where near as blotchy as it looks. But it's not bad for a Jpeg.

It would probably be good to reduce error_bound for stronger shadowing
effects, but you would have to increase count to avoid artefacts at the
same time. For a more detailed suggestion i would need to see the
radiosity settings and the finishes of the objects.
concerning printing:
I had my last high quality prints on a3 paper made with a image width of
4800 (that's just below 300 dpi). Printers for large posters surely do
not need that high resolution, but the best would probably be to make some
test prints if possible.

I lately finished my first a3-printout. It was printed in an
advert-design-shop on a A3-Photo printer. It has about 1440dpi.
I rendered my image in a 9900x7200 resolution <must be around 600dpi>.
You sould set a weak antialiasing:
Antialias_Depth=2
Antialias_Threshold=0.4
On my printout, there are no pixels & "stairs" visible.
The POV-generated PNG was 15 megabytes large.
You had a fine idea there.. are the lights in radiosity or in
arealights??

Here are the radiocity settings I used:
assumed gamma 1.1
brightness 0.80
pretrace_start 0.04
pretrace_end 0.002
count 300 (I tried settings as low as 100)
recursion_limit 2
nearest_count 7 (I have tried 1-7)
error_bound 0.4 (I have changed this from 0.7-0.4)
There is a light outside the room, but most of the light is radiocity
light coming from a 100 unit sphere with a texture with ambient set to 8.
I will now try to render it with an error bound of 0.1

Have you tried it with recursion_limit 1 ? That should lead to more
contrast, but i'm not sure if it would look better.
