In addition to Night Terror and NME (like @susmitds said), look at Darkstride. Night Terror and NME reduce your detection radius, while Shadow Dancer and Night's Silence ignore the speed penalty of sneaking. Shadow Walker is also out there, but its more geared towards a PVP gank build.
If I were to go stamina, it would be Night's Silence 5 piece, NME 5 piece, and Night Terror 3 piece. I disagree with Jailbreaker because you can't get to the minor expedition buff. Night Terror's 3rd piece gives you the detection radius buff.
But I would only do this for the Thieves Guild and Dark Brotherhood quests. This isn't going to do much good for group content.
