Best bet is to find a local tackle shop and speak to the guys in there.
If your rod is only 2m then that's about 6 and a half ft so beach fishing is gonna be a problem. I'd fine some rocks or a harbour wall to fish from.
Buy some spinners or feathers if the mackeral are about, which they should be at this time of year.
If you want to bait fish then Black Lug or Rag worm would be your best bet for general fishing. And if your fishing from Rocks or a Wall with a short rod, you'd probably be best off with a float.
Find a hook size to match your bait. You'll need at least 15lb line but all this needs to match the rod and reel that you are using. This information should be displayed on the side of the spool on your reel.
