My advice is to get them as chicks (under 4 weeks, but make sure they are pullets (female). Get whatever breeds you want, but get them all at once. I wish someone had told me that in the beginning, I'm having issues merging my younger Orpingtons with my older Easter Eggers.
I LOVE all my birds and they have great personalities. We have Easter Eggers who just started laying. They come in pretty feathering colors, you can find them at any feed store, and they lay pretty colored eggs. My orpingtons are VERY laid back, even the rooster--although he's loud, which is why you want to make sure they are all pullets-- living in a suburban area. We are attached to them now that they've grown up and we know that some are roosters--so we're stuck with crowing contests between my Orpington Roo and a Silkie Roo. Thankfully we aren't the only ones out here with loud animals. My roosters make the same amount of noise as my neighbor's goats
Silkies are great personality wise, but you may end up with a rooster since they can't be accurately sexed until they are older. (We ended up with 2 cockerels and 1 pullet out of 3 we got as chicks from a breeder)
As far as the smell goes, if you make a well designed coop (see the coop section), follow the 4 square foot per chicken rule, and keep it clean, the smell should stay contained to the coop itself. Mine doesn't smell at all--though so far only our three EEs live in the big coop.
Good luck and Enjoy!
