I very much second (and third) fballatores advice and other good advice, and also try to stick to your equipment for 6-12 months if it is reasonable. By then you will be at a much better position to judge by yourself what is suitable for you.
But keep your sax in good repair, a small leak makes it so hard to fight the horn in the beginning. Feel free to try out different reeds though, they would not cost you an arm and a leg
Try to find friends that share your interest, if you are anything remotely similar to me, you will already know a lot of people that play some kind of instrument. Just ask around, you'll be surprised! Playing together is great fun and great practice.
What size of sax do you have, I play alto and am a beginner like you.
Make small targets for yourself, do not be too ambitious. Be prepared for stalling or even bad days and weeks. When going backwards stops, you grow and feel great, for a while
But most of all, make sure it is fun! Playing saxophone is a bit like sailing, the journey is the purpose, not reaching port. Therefore play something you like, or go watch YouTube for inspiration. You might rediscover a lot of great "old" music. Enjoy.
SOTW is also a great place, use the Gary-button (also known as the search button) will bring up tons of good advice. Just do not forget to play once in awhile.
Welcome and good luck!
