1. Right and left bank are usually depicted as you stand in the river and look downstream/the direction the river is flowing. As opposite banks are often ran by different estates/clubs they just refer to where they have the access from - you can still wade out in to the river.
2. You pay per angler, it is the person that has paid for the right to fish regardless of how many rods he wants to use. You will likely see when you visit in July, that many anglers carry a few rods with them with different set ups. Personally I often have a dry fly rod set up for if I see any rising fish, and also carry a spinning rod depending on what the water is like where I plan to fish (sorry to mention spinning on here
haha).
