Canon 20d focusing issues

I just posted this on rec.digital, but this is probably a more
appropriate place for it.

Hello,

Let me start off by saying I'm very new to photography. I bought the
20d to take to Europe in hopes of getting some large prints made. It's
my first D-SLR. Ever since I bought this camera I've had trouble
getting photos to come out well. I don't think I've really ever gotten
a photo in a 'mode' setting to come out clear. I always have soft
edges and overexposure. I tend to shoot mainly in manual mode, but
sometimes still have problems. My biggest issue is getting focused
clear images. If I'm just taking photos of friends around town, I
typically set the camera around 1/100th (in the time-priority mode) of
a second to keep from blurring the shot with my unstead hands.
Sometimes this works, sometimes it doesn't. Recently I went to a
wedding and did this same thing, and almost every photo I took came out
blurry. Now I have taken some crisp shots, but they are almost always
from far away on nice sunny days. I like to go hiking and take the
camera, but the dark woods don't always make the greatest shots.

Here are two photos I took this morning on my couch. The data from the
shots follows. The first shot was in AE mode set. The second was in
fully automatic. Notice how soft the edges are on the fully automatic
shot. This is what keeps happening every time I take a photo. Does
anyone know what is going on, or care to suggest how to resolve this?

turn down ISO from last night, a little grainy)

Here's a shot from the wedding that came terrible just to show you what
I'm so confused about.

Thanks for any insight, -Todd
