The correct way to describe them is either: OS X Leopard and OS X Snow Leopard or OS X 10.5 and OS X 10.6.
Tiger is OS X 10.4.
I do not think you have the technical ability to download, install and use SheepShaver to run your Quark and Photoshop, but be my guest.
Here is a post that I listed that explains them in more detail:
With the newer Intel Macs, you have to run a Classic emulator such as SheepShaver, which requires you to extract the Mac ROMs from your older Classic Mac and then install Mac OS 9.
A related program is Chubby Bunny, which comes bundled with all of that included.

The download link to Adobe Creative Suites 2 is an updated version of Adobe Photoshop and Adobe Illustrator (which may be able to replace Quark) that Adobe now offers for free download and may solve your problems. However these are older PowerPC programs that require Rosetta to run (that is, on Snow Leopard installed with the optional selection for Rosetta either on a separate partition or a separate hard drive or in Parallels).
On the other hand, you can purchase a more current version of Adobe CS (3 and later) which will run on your 2008 MBP running Mt. Lion.
I think that we have now covered ALL the possibilities!
