I have an ASTA repertoire list that sorts pieces into levels. Of course that's a little artificial, and you could work on things from several levels at once, but it's a start. According to this list, P & A is in level 9, the Bruch is in level 10, and the Monti Czardas is back in level 7, and Accolay is 6.
Here's the full list of level 8. If there's anything from it you haven't played, I'd do that.

I should mention that when it lists the Bach Sonatas and Partitas, they're not all of the same difficulty. I'd start with the Allemanda and Giga from the D minor Partita, and then the E major.
Some of the pieces on that list are pretty big deals. The Vitali Chaconne in particular would prepare you well for the Bruch, giving you some practice on octaves and even tenths.
