You'd be much better off with a pole, but bearing in mind that's not an option, a waggler set up will do if it's not too windy.
Try a 2BB or 3BB Drennan Stillwater Blue with only 1mm of float tip showing. Having, say 3mm showing, will mean you are likley to not even see the bites.
Put all the shot around the base of the float and have 3 No. 10 shot spread 10" apart so that the last one is 10" from the hook.
Mainline of around 3lb is ideal (I use 2.6lb Bayer Perlon) and hooklinks around 2lb. 1.7lb Beyer Perlon is good if you don't like pre stretched lines, but I prefer Preston Innovations Reflo Powerline - 2lb 10oz 0.10mm. I tie my hooklinks to 9" exactly so if I need to replace one with another I won't have to re-plumb or change my rig.
It's really important that you plumb the peg accurately. I look of a gently sloping bottom at around 6m to 12m.distance. This is where the pole can score much better than the waggler.
I would start off fishing exact depth and work from there. That means that if you are missing bites I would try 4mm shallower, or deeper. When you get it right you should start hitting most bites and landing fish. If you land fish and teh hook is only just in the lip, or even outside the mouth then it's worth tweaking the depth.
Don't worry too much about bait. Maggots, Casters, Squatts and Pinkies will all work. Corn or small cubes of meat can be good if other fish are a nuisance. On waters where pellets are often used these can work a treat. If this is the case on your water try some expander pellets (I quite like VDE Ringers).
Just feed little and often - eg. 10 maggots every 3 minutes or so. And recast as you feed. On good days it's worth casting, feeding, waiting for teh bait to settle, counting to 10 and starting the process again.
Just to re-emphasise - teh two most important bites are to fish fine, with the float dotted right down and to get the depth exactly right.
I hope that helps!
