Liam typical rule of thumb 0.1 gram of float per foot of water,
I would start off with the Garbolino range of floats as they are cheap and robust the DC6 is ideal as it can be used tight up against features down the edge or down the track, they are also quite stable.
Your going to need a range of lines from 0.13 to 0.21 I would go for preston powerline or similar, to kick off I would set all your rigs up with stotz and ignore olivettes for the time being as srotz will cover both situations to a degree.
Thats 1 salmon and cucumber sarnie you owe me
