This isn't directly related to the topic, but I thought I'd say that the best resources you can find aren't what you'd find in a VCE bookshop (and what you seem to be asking for). To gain a greater understanding of the subject, I'd recommend that you read the following books:
+The Cambridge Encyclopaedia of Language
+ Blooming English and Weeds in the Garden of Words (By Kate Burridge)
+ Euphemism and Dysphemism (Kate Burridge and Jean Mulder, methinks)
There's more that I can't remember, but go to your local library and borrow as many linguistics books as you can. It really helped me - I skipped the 1/2, but I started the subject with broad knowledge, examples, quotes and a decent understanding of metalanguage. If you have good English Language teachers, they'll probably photocopy a lot of newspaper articles and online resources for you to use throughout the year, but it's also a good idea if you keep your own journal to refer to for SACs and the exam.
