Well I will be using OCTree for Frustum Culling and will create BSP Trees for each cube for Z-Sorting. Is it good for a start or should I use BSP Trees both for Frustum Culling and Z-Sorting. Any suggestions ?. Plus any hint/help/tutorial on chosing a polygon for split in BSP Trees ?. Any kind of help is highly appreciated.

Best Regards,

The BSP FAQ answered these questions and gave sample code. Here are direct links to your questions:

Q: How Do I Choose The Partition Plane?
A: FAQ Section 7 (Read all of section 7)

Q: Should I use BSP Trees both for Frustum Culling and Z-Sorting?
A: Z-Sorting is done when you render the tree. FAQ Section 9 (Read all of section 9) For frustum culling read this thread (a lot of it discussed in the FAQ too).
