At any point you can manually generate output products by selecting the IP from IP Sources, right-clicking and selecting Generate Output Products.
The default flow when generating output products is to create and launch an out-of-context (OOC) synthesis design run for the IP. This results in the inference of a black box for the IP when synthesizing the top-level of the design.
FALSE, and the checkpoint is not created when the output products are generated.

Xilinx recommends that you use the default OOC to reduce the run time on synthesizing your design. When using the OOC flow, you do not need to synthesize the IP every time you run synthesis during development.
