Yeah, no disrespect but I get the feeling maybe you're not the best person for the job if you don't know what software to use...
But yes, you need Adobe Creative Cloud membership. If you don't want the full membership, you'll need Photoshop, Illustrator and InDesign. No one really uses Quark anymore (perhaps that's what you learned on?). With the Creative Cloud membership, you can install on either a Mac or PC platform, and if you have two systems, you can actually use the software on both -- but no more than two systems.
