24 hours in LA

Hi folks,
In August I'm hoping to fly SYD-LAX on a QF reward flight, returning back to London on VS20 out of SFO a few days later. I know San Francisco pretty well so am hoping to spend a couple of days there, but have never visited LA so am after some advice.
I could plan to fly straight onwards on arrival into LAX but that seems a bit of a wasted opportunity to visit the city. Also, tiring after a long inbound flight, and unpredictable with regards how long a delay I should factor in for the connection (it would need to be ticketed separately).
So, if I decide to spend ~24hrs in LA what are the top tips? Where's a sensible area to plan to stay, that's fairly easy access to both the airport and the major touristy sites? Any thoughts about how best to spend the time much appreciated
