If you have a pre formed pond, it probably will have shallow shelves each the edge, perfect for your marginal plants but not wildlife friendly.You will have to make a beach at one end/side of your pond. This will make a gradual entry and exit point for all wild life allowing birds to bathe and drink; frogs to spawn and hedgehogs to get out safely (they often drown as they can't manage the slippy,vertical, plastic sides of a pond)
You can do this by adding a combination of stones, bricks or large cobbles to one of your existing shelves until they are above water level.
Your plants sound great and I'm sure you have more than enough. I can never understand why water plants are so expensive as they grow so fast. You will soon be dividing your lily (a couple of years)and lifting out pond weed as it overtakes your pond at the end of the summer!
You can use aquatic compost to plant your plants in or poor garden soil that has not had any fertilizer added to it. As the introduction of nutrients to the pond will encourage algae to grow. Set any plants you are going to add in the shallows so they can soak up the water before you lower them deeper into the water to stop the soil floating out of them. Mulch the top of your pots with a good layer of large gravel.
I would also invest in a water butt or two to top your pond up from so you are not adding any more tap water to the pond and therefore more nutrients.I attach the hosepipe to mine and it fills up my pond when the levels drop.
I seem to have got a bit carried away here but I would have liked to know this sort of info. when I set up my pond....which is now very successful
Good luck and enjoy. My pond brings me a great deal of pleasure along with a lot more species visiting my patch.
