MacBook Pro, Mac OS X (10.6.8)
There is no 10.6.9. But if you want to install Lion, download it from the Apple Store. There is no installation disc. You can buy a thumb drive to install, but it's only $30 in the App Store.
Be sure your computer meets all qualifications and requirements for Lion.
Also, Lion will not run any PPC applications. Be sure you check all your software.
You can also create your own thumb drive installer:

The big issue upgrading to Lion as with any operating system beyond Lion is the lack of Rosetta:
