I was wondering if anyone could suggest some appropriate dynamics? The Watson Forbes edition is marked 'poco f' at the beginning of Bourree 1, 'p' at the beginning of Bourree 2 and 'p sempre' at the beginning of the second section of Bouree 2. Are there any other places where it would be appropriate to change the dynamic level?
Also, the last quaver of the fourth complete bar in Bourree 2 is an A natural (an accidental is marked as it's in the key of C minor) but there is a flat sign in brackets above the stave over that note. How should I play that?
The dynamics in the Watson Forbes edition are only editorial suggestions so you can ignore them if you don't like them. I think the flat sign in brackets above the stave over the note in the fourth bar of Bourree 2 is an optional way of playing that note. The Watson Forbes edition is based on both the Anna Magdalena Bach manuscript and the Bach-Gesellschaft edition of the suites. It is possible that they disagree about that note.
One way of working towards your own interpretation of these pieces, including dynamics, is to listen to lots of different recordings of them, and decide which you like/ don't like, then work out exactly what it is that you like or dislike about them. This should give you a much better idea of how you want to play them. If you listen to several recordings you will find that there is no single correct way to play these pieces, different performers have very different ideas. You could also try playing them in different ways yourself to find out what suits you.
You could also try having a look at different editions of the suites for different ideas, for example another scholarly edition for viola is the Simon Rowland-Jones edition. There are also some versions that you can download free.
