I fine an 8w is a pretty good allround weight and is handy in a little breeze. You could go 6w, but an 8 gives you a bit more stopping and casting power.
I would keep an eye on ebay, trading post, local rag, etc and buy the best rod you can afford. Buy a reasonable quality line and the reel can be a cheaper one for the type of targets you are chasing. Suggest you get a saltwater compatible version as this will save you hassles.
I started with a Gillies starter combo and it was fine to handle the fish you are talking about. You will appreciate the better casting qualities of better rod though, so can upgrade later if you go the Gillies path.
