OK. A news item to get you thinking. Answers in the comments.

First up, an easy one:
I eee oai o ooa a e ooi eee o oe.
Ths sntnc cntns n vwls nd th prcdng sntnc n cnsnnts.

Also easy:
Siht ekil ti gnidaer eb d'uoy ,werbeH ni erew ecnetnes siht fi.

Even better:
fi siht nes-ecnet erew ni beh-wer dna tes ot um-cis, ti dluow kool tsuj a til-elt ekil siht

And harder:

Very good.

Also, the sentences are supposed to be self-referential - like my current display name: "This sentence contains two erors."

Or:

"This sentence no verb"

Or:

"I tried my best not to mention pink elephants in this sentence"

(examples thanks to GEB)

Got the first three, and the first part of the last one, but I cannot for the life of me read the second bit. Google doesn't even turn anything up!

Well, with the help of urban dictionary, I get:

f u cn rd ths, itn tyg h myxbl cd
If you can read this, I think not there you go heroin (myxbl) compact disc.

Not that any of that makes sense.

Hint: It's a GGBJ

And 'GGBJ' predates UrbanDictionary.

please explain last puzzle. it seems to me to be a sort of joke as the second part may refute the first part by being unintelligble. im not sure however so please help!

Yep, you're almost certainly right; it's a green golf ball joke, a shaggy dog story, a "no soap, radio".
