I had no option to turn on each buddypress plugins

BuddyPress is now considered a single plugin. Once you\’ve activated it in the Plugins menu, you go to the BuddyPress menu group at the bottom. Click on “Component Setup”, and you can enable and disable each component separately.

where should bp-custom go? the same dir as buddypress after r1303?

That is correct.
