Joanie that sounds very normal to me. Try not to project how she is acting onto what you think the toddler years will be like. She is not trying to manipulate or frustrate you. She is frustrated because she is not as independent as she wants to be. She is excited because she has these new tricks to try out. Have you read a book about development yet? It really helps to understand what is normal and what the child is experiencing.
Dylan sometimes does the same thing. I lay him down after he dozes off, and his body automatically goes into crawling mode. It's frustrating for me, sure, but I think the cause of my frustration is that I have a million other things to do (clean up the kitchen before bed, go do my work, go put my older son to bed, go to the bathroom, get myself ready for bed, etc etc etc) So if he is not upset and just thinks it is playtime, I leave him in his pack and play to work out the giggles or whatever, and I go do whatever it is that I wanted to do. I leave the room dark so he knows it is nighttime, and that I am serious about bedtime. I go wash my face or put son #1 to bed or *whatever* until Dylan is starting to fuss. Then I go back in and try to walk him to sleep again. Rinse. Repeat if necessary.
If I just stay in there and try over and over and over to get him to sleep, I get frustrated and stressed out. It's not worth my sanity to do that. It's just not.
On nights when he has taken 3 naps that day and there is no bedtime in sight, I let him stay out in the *dark* living room with me while I do my work for the evening. Dh hangs out with him quietly for a bit, until he is ready for bed.
With our first son we were VERY regimented about bedtime being bedtime no matter what. And it drove me crazy when he wouldn't "comply". But babies don't always comply. And the point of parenting is not to get him to obey me or comply to my orders or whatever. I am gently teaching and guiding him. But if he isn't tired? Like, truly is not ready for bed? Well I'm not going to force him. I still keep things quiet and calm and dark, so his body is still heading towards sleep, but I can't force him to sleep. Same for my 3 year old. He goes to bed at the same time every night. But on the off day that he takes a later nap? Well I still put him to bed at the same time but if he plays quietly in there before falling to sleep, I don't care. I can't make his body tired. 
So anyway.... A very long-winded way to say don't sweat it. Let her work out the urge to move or whatever in her crib while you go wind down yourself. There's no way I'd be bouncing a baby for an hour and a half, if he wasn't upset. I did that with #1 and it was a giant waste of time. Sometimes being with your baby is stimulating enough for them that they can't wind down. I've found that leaving them to play for 5 minutes or whatever without me in the dark room helps a lot.
Good advice here! Also from Katie. I am so much more laid back about getting Jasper to sleep. If it's not happening, I give up and let him play downstairs with me. Once it gets too late, I put him in the carrier and bounce him on the ball.
