Totally normal! My daughter was the same way at that age, her daycare provider (20 years experience, and so incredibly knowledgeable) was very reassuring and let me know it's common when babies are gaining mobility. It did get tricky when she learned how to pull herself up to standing in the crib...she thought it was really funny and would do it over and over again. We would just check on her occasionally, and when she was finally asleep, we'd put her back on her back (although she was definitely a belly sleeper, still is) and tuck her in.
I'd say by the "taking forever to settle" stage lasted about 2 weeks or so. We just made sure to keep the nighttime routine VERY consistent, so she would know bedtime is still bedtime. When she was pulling herself up (around 9 months), it only lasted a week or so. By the time she was 11 months, she went to sleep and stayed asleep.
I'd avoid the fragrance laden lotions previously mentioned to "calm" him, get an essential oil diffuser (available at most health food stores) and put a drop or two of lavender oil on it. It's the scent of lavender that helps babes settle, and putting it on boys has had some strage effects in rare cases (like breast development). Plus most mass-produced lotions have pthalates and parabens in them, two ingredients that the FDA will (hopefully soon) decide on regulating their use in children's products due to their hormone disruption tendencies.
We also, on occasion, used chamomile tea (diluted) on those days where she was overtired and cranky to help settle her down. Chamomile is amazingly calming, you can even find "calming" drops at most health food stores that have chamomile and mint since both also sooth the tummy. Teething tablets and Colic tablets by Hylands are also homeopathic and help calm. We really only used those when she was "out of sorts" and not feeling too well, or teething.
Good luck! These phases are so short in the grand scheme of things... pretty soon you'll be potty training!
