Heck yeah buddy! Welcome to the sport! I'm a big proponent of getting lessons if you can. No matter what your ability is, from beginner to seasoned racer, there's always something you can do to progress. Barring that, it's hard to give tips without seeing your form. But if you post a video, I can help. I'm sure that there are resources online that I'm unaware of.
Many ski shops have summer sales on gear, so if you get on their mailing lists then you can get deep discounts on equipment in the off-season. I haven't bought anything full price in years.
