Support:

Mao: Nice zoning potential with sapplings if you can handle the mana...otherwise he still has nice cc if you want to rely more on Q and W. With the current PBE changes he will be even more suited for this role.

Zyra: zone with plants, initiate fights with E. Her ult is the icing on the cake.

Karma: can be a poking "bitch" if you manage to hit er Q+ult combo well.

Nami: your enemies have one choice: farm and get caught in your bubble or dodge. Also her E facilitates chases and if you can cooperate with your lanemate, you can W-heal him while poking with the bounce. Her playstyle can sometimes come close to Sona's (from my experience).

Jungle:

Vi could be for you: AD with nice ganks and a good clearing.

I could add a few other possible junglers, but she seems to fulfill every requirement you asked for. :)
