I wouldn't worry for Forest too much. Too many signings, probably, but they're on a great run under Cooper, and I think they have the game smarts and determination that will see them pick up points. Home form will certainly be key but I'd fancy them to have a good record at the City ground. Very early days but wouldn't predict them to go down.
Bournemouth look like goners already, and it might be harder to predict with Fulham, because 5 points from 9 is a good start for them. Ultimately I think they could do with a couple more players, but get them right and they could stay up.
If Leeds improve this season, and I think they will, it'll be cause for some Worrying Times™ for Frankie's Blues™ - Regardless, I think it's going to require slightly more points this season to stay up, which should be cause for concern anyway because their starting XI has gotten worse, and this time it's Lampard from the start. As I say Leeds seem to be the ones right now who'd concern you if you were an Everton fan, but it's only a good start so far for them and it could go either way. The likes of Brighton have came up and are doing better than them on a budget far smaller, Brentford are threatening to do the same, too.
