In general, I've found that planting near wild ginseng is usually a good plan for woods grown plants. It seems to me that the plants will grow in a zone on a hillside. What I mean by that is, I might walk up the hill from the plants, and down the hill and not find any more. But if I walk across the hill, staying at the same altitude(via a topo map)I'm likely to find more plants.
As far as your seeds, I think the others have covered this well.
For slugs, they don't like copper. If your raised beds have \"walls\" of wooden boards or the like, you might try putting copper on the top. I've never had a problem with slugs, but often though I'd try stripping out some home electrical wire and staple that to the top of the boards. Just an idea.
Good luck.
