If you can afford a hire car, that will make everything a bit more efficient - we did it without a car last year, and spent quite a bit of time hitching. We stayed below gandalf which is best if your carless. Without a car, it took us 2 days travelling either way, camping at the airport.
Lots of gear as the previous poster said, the more cams the better - protection is generally really good.
We were there in August last year, got a bit rainy towards the end...probs july is most popular.
Do westpilleren, it's amazing!
Fish from the bridges when you can see schools of cod below them.
