Rgd stroller, if u r looking for a light weight stroller, do remember not to hang too heavy items at the push handle part. I have seen silly parents did that n the stroller topple over with the bb inside! For me, I m using capella for stroller. Not a too light stroller but it's a single hand closure system n can stand on its own once closed (ie dun need to lean on walls).
As for car seat, I m also using britax. Choose one which can be used from infant up to save $$.
My one cannot be omitted item is my bb carrier! In fact most of the time I use my carrier rather than stroller as its easier for me to move within crowds. Better brands for carrier are ergo n Beco which gives very good support for both bb n parent.
