Basic AWS IAM permissions for an S3 bucket

I'm trying to figure out a basic permission set for an IAM user/key to have to have access to only a single bucket in S3 - only read/write access on an individual bucket.

What set of permissions is the minimum required to make this work? I have all options selected in the IAM policy generator for S3, all permissions enabled on the bucket except CreateBucket and DeleteBucket. I've also created a set of keys specific to this user.

When I try to access the bucket with these credentials, I get a problem listing buckets, even though the ListAllMyBuckets property is enabled.

Anyone have any experience setting up a basic bucket config like this? Seems like it would be pretty common...
