Advice...

I need some advice on car seats/strollers, etc. We have seen a couple car seats we like that have gotten great reviews. There is one that holds up to 22 lbs and one that holds up to 30 lbs. They both come with the stroller combo. Does anybody have any recommendations on whether to get the 22 lb or 30 lb and if it's beneficial to get the stroller combo??? Too many choices, this is overwhelming. :)

Thanks!!
