For your L.A. leg, Long Beach is fairly close to Lakewood and October should be "off season" enough that the rates are pretty good. I'm not sure there even are any hotels in Lakewood proper...at least not that I can recall.
Depending on your budget, the hotels on Ocean Avenue are pretty nice and you can get an ocean view.
If you're looking for something farther to the north, the Marriott near Long Beach Airport would put you closer to Lakewood but it's not really near anything fun (walking distance, that is).
The advantage of staying on Ocean is that you can walk to all kinds of restaurants and there's a big entertainment complex called The Pike that has movie theatres, etc. (Plus you can see part of the Long Beach Grand Prix course.)
If you really want to splurge, check out the fairly new Avia Hotel. It even has a rooftop pool with views of everything.
