If I understand right, you mounted "A" on some mountpoint of "B".

What you now need is to be root to deal with (most) files on "A" because they 
are owned by root, or anyway not by your user.

I would install Gnome Commander on "B". Once you are running GC, you have a 
menu point to open GC as root. Enter your password and you should ne able to 
browse, edit and delete files on "A".

If you are told you don't have enough rights, maybe sudo is not enough and you 
should give root a password on "B" so as to really be root completely, but 
most of the time sudo will do.

(I regularly do this sort of thing, even between different distributions).
