well, good news bad news I guess
you have there a wonderful loom. It would be wasted on ragrugs but you will be able to make some beautiful, highly patterned fine weave rugs and wall hangings.
(that was the good news!)
the bad news is, you will really need to enrol in a class to learn how to thread it up!
Sorry, I didn't note where you were posting from, but in if in England the weavers guild should be able to put you in touch with someone who can teach you both spinning and weaving. They will also have information on home made vegetable dyes etc.
Please don't be disheartened....once you learn the threading you will be spellbound! There is nothing quite like watching a beautiful piece of weave grow
