So the main things I should do is up the shutter speed (or add a tripod) and increase the aperture to 11? I was afraid of bringing the aperture up too high because of all the things I read about difraction...

No — sorry, I was a bit unclear with my terminology. The bigger the aperture number, the smaller the aperture. With f/11 you risk a bit more softness, as well as a higher ISO or longer shutter speed, which are all bad for sharpness. But softness due to diffraction can be counteracted by adding sharpening.

For this subject, you might get away with f/8, which is a wider aperture opening, if you focus on something midway between the nearest and farthest objects you want tolerably sharp.

If the f/numbers are still bewildering, try taking a photo while the camera is pointed at you — see how the aperture size changes with the aperture setting. A big number will give you a little hole, and a small number will give you a big hole.

Also, I just realised this was actually a very bad spot to stand for taking a photograph. This picture had to be taken at 1000ISO to just be able to get a 1/100 shutter speed. I guess this is to blame because I was standing in a heavily shadowed area?

Do you have a tripod? This ought to solve your problems.
