I just want to bump this to add that I was dealing with the same sleep-fighting issues and have overcome them to some degree.
Basically, I just started catching the sleepy cues really really early and would go tuck her in bed and pat her back and drone "Sleepy time, sleepy time" until she'd drop off.
I ONLY put her to sleep in one place - her side-carred bed next to mine. It only took about three days for her to catch on that being laid down there meant sleepy time. She's going down a lot faster these days - maybe only 20 minutes of droning and patting, rather than an hour or more with constant fussing.
But I swear, you have to be vigilant! That very first yawn, or droopy-eyed look, or the 7-mile stare, and off we go. If I wait and try to do one more thing, she gets more agitated and is so much harder to put down!
I'm also teaching Dh and everyone who interacts with her to follow her cues - and to not try to "jolly her" out of crying. Over stimulation is our main issue, and the only way to combat it is sleep, I find. The reason we had such a horrible first month is because we didn't realize this, so we'd try to do all kinds of stuff to get her to stop crying, rather than to help her to sleep. She just needs to shut off and shut out for a while, and only a nap can do that.
HTH someone!
