Help Me Use My Camera

Background (Not necessary to read this bit to help me)Disclaimer - I know b*gger all about photography.
I've had a Sony T-9 (I think it's that one) for about 4.5 years.
But noticed that low light shots were pretty rubbish.
Been wanting to get a better camera for a while - especially for taking low light indoor shots, and nightime scene shots whilst out and about.
Wasn't tempted by an SLR cos they're too big to lug around.
Liked the idea of micro 4/3 but GF-1 and EP-X models are not all that small.
Loved the the look of the new Sony NEX-5 but quite pricey with 2 lenses, a lukewarm review on DPReview and the fact it's not yet widely available put me off.
Looked at the Panny LX-3, Samsung EX-1 and Canon S90.
Got the Canon S-90 in the end cos of great reviews and relatively compact size.
Also got a case and 8GB card.

My ProblemI am flying abroad on Monday, back Thu, then off on Sat for a holiday with the missus.
There's no proper user guide with the S90.
Only PDF files on DVD - like I am really gonna sit there and peruse thru' those
I need a quick guide on how to use this camera specifically or these types of slightly superior point'n'shoots in general.
I need a portable guide which I can refer to whilst I am on travels - printable couple of pages or preferably an iPhone app
Can anyone point me in the right direction?

Additional AdviceProbably gonna buy one of those gorillapod things - have people had a positive experience with them?
Any other tips, comments

Thanks in advance for any advice
