Interested in Gaudiya Vaishnava literatures

[Krishna Susarla]

Can anyone tell me if there are any good translations of the following
books:

ShaT-sandarbhas by jiiva gosvaamii
vedaanta-shyamantaka by baladeva vidyabhuuShana
govinda-bhaaShya by baladeva vidyabhuuShana

Also, I have heard that Baladeva Vidyabhuushana wrote a commentary on
Bhagavad-Giitaa. I would appreciate it if anyone could point me in the right
direction for acquiring copy.

I am interested in translations which have both the Sanskrit and English.
But if I can only get them in separate Sanskrit and English publications,
then that would be adequate.

Thanks in advance,
