Masking: making a selection around an object or shape which then allows you to edit the part of the image within the selection area, while the parts outside of the mask are protected from change. Sorta like using masking tape.
Hue and saturation: terms for referring to differences in color values (what color and how strong a color is). There are really wonky, technical definitions but here's my attempt at putting it in layman's terms. Hue really is just another way to say color. Seriously. Saturation, as the word itself suggests, refers to how much of the color is in the color. We change the saturation of a hue by "adding or subtracting" white or black.
Here's a link to a site that breaks it all down fairly well:

Filter: pshop has a ton of filters that can be applied to create different effects. One that would be useful in this context is render/lighting effect.
Here's a simple, flat graphic:

A lighting effect would give an effect something like this:

A lens flare (another filter in pshop) refers to a highlight of the type you get when you take a photo out in the bright daylight, facing the sun, and you get one (or more) of those bright spots or halos of light in your image. Like this:

You can see in the image below that there are a couple of highlights on the hub -- the white spots. Without those white spots the image would look rather flat. Those are referred to as "specular highlights." If there's no specular highlight in an image, it appears flat and unnatural. You can create spots like this using the lighting effect filter, it just takes some practice. Or you can "paint" them onto your image by slowly building up spots of white.

I'll shut up now...
