Barricade is still known as a top tier shoe, but get anything that feels good and stable. Unless you're going pro, a shoe doesn't have to do much other than keep your ankles stable while moving side to side and last for a while.
Racquets, my advice is find a shop that lets you try them out free. You'll have the dual benefit of experiencing the racquet before committing to one and also potentially being able to snag a deal by buying a tester. Got myself an $80 Babolat Pure Strike Team last year, much nicer than strictly necessary for casual play, but cheaper than even a less competitive racquet. Ultimately, I'd say most important is finding a good shop, and then finding good gear should be easy.
Congrats on getting back into it, and enjoy!
