the nightwatcher doesn't always give you what you asked for, she gives you what she wants to give you, but Dalinar says he knows what his boon was. So yeah, I don't think the Nightwatcher gave his surgebinding powers either.
And if he isn't already bonded to spren, he will be shortly I'd imagine, possibly giving up his shards will allow him to attract a spren, since we know Syl doesn't like Shardblades, Dalinar's having the shards may have been preventing him from attracting a spren.
He may attract a different kind of spren then Kaladin, he doesn't seem as fixated on protecting as Kaladin is, what he's fixated on at the end of the book is building a proper alliance between the highprinces. I think Resolute/Builder the characteristics for the 8th order fit him.
