A quick hintthrough of the remaining clues:
3. - Spell the water the old way - with a kick!
Two words of this are a straight clue; the rest is orthographic.
5. - Go back to noodles with a different filling - sounds like a police siren?!
'different filling' indicates one letter has been changed.
6. - The east is red - or a vowel vehicle in back.
Everything after the dash is just me spelling out the word; it can be broken into four parts (and you already know that 'vehicle' = car).
7. - The first is the least. The pirate agrees, so turn it on its head.
"The first is | the east. The pirate agrees | so turn it on its head". The last part is neither straight nor cryptic; probably best to ignore it.
9. - Rings around the lower back.
The cryptic clue here is 3 words long and points to a single English word.
11. - A chemical in a swamp? Send the shepherd away to find the lamenter.
The misspelling of 'shepherd' was unintentional. ^_^' Find two words and then remove one; there's only so many 'shepherd' options in Middle-earth, right?
12. - T. rex bangs it, the first gnomes start to end - this comes first.
The T. rex in question is not the dinosaur.
