I bought Order of Battle Pacific and few other games a while back, and only recently got to it. In another thread someone mentioned versions and DLCs. Questions:

1. Were there any patches for Order of Battle Pacific? If so what is the latest version?
2. DLCs, do I need to buy all DLCs(any lists?) or just the latest?

Latest version is 2.2.5. You can update from the menu screen.
You don't have to buy a DLC to update, the main version is always updated when the DCL is published.
The DLCs will be sold separately, currently only Morning Sun has been released.
There's a Marine Corps campaign being beta-tested now.
