Hello Corpse, welcome to Subeta :)

The Newbie's Guide that's stickied to the top of this forum is very helpful for beginners, and there's always the help forums for more specific questions. As for the questions you asked here, inactive pet means that the pet isn't the one you have actively "with" you as you explore Subeta, and isn't eligible for some of the events, like stat rewards from Oracle Quests. To make a pet active, just go to "Pets" on the left-hand list of links on your page, under "Personal". Click the pet you want active, and there should be a link beneath it on the next page to "Make Active Pet".

And yes, you need to buy the clothes if you want to wear them.
