Welcome to Epic,
Starting and learning on beginner equipment is best.
The many function is that it easy to initiate the the skills required in skiing and that the equipment is forgiving when mistakes are made (as you will make them as you start out). This helps you develop the skills need to improve by allowing you to make errors and not be punished by them.
As you move up the level , the equipment becomes more responsive and less forgiving.
Even higher up the equipment becomes responsive to the point of twitchyness (as it has little or no forgiveness on errors made). A good example of this is full blown race skis (tuned to the max), fast and precise as can be, but you so much lose concentration they will bite you (HARD). Trying to learn on this just doesn't work as you can't initiate the skill set without being punished for it as a beginner as the skill set has to be perfect (remember slightest mistake, extremely hard and immediate punishment)
The other issue purpose, beginner skis are designed to be all around carving skis for the most part. You want to get good basic skills first. Park skis, twin tips, powder skis etc are designed for more specific applications and in some cases can greatly limit your ability to learn proper technique.
So, consider the following:
1. Good fitting boots (you don't have to break the bank, but don't buy something at this point to far beyond your ability).
2. Bindings (anything where you fall within the DIN range (very important) to prevent injury.
3. Skis honestly consider something in the beginner/intermediate range and no more at this point. (used in some cases can be OK, depending you how fast you are looking to progress). Also get the skis more towards a general application to start, specialize on the next set maybe.
Something that might be better could be something like this (again without knowing your age, ht, wt and sex, yes women's skis can be different) I'm only giving an example:
for about the same as what you paid for the other ones (and bindings are included). Local shops can on occasion have similar deals and at that point support them. Don't forget they are looking to get your repeat business and they will provide your technical support.
Boots, get fitted at a good shop, the few extra dollars are worth the investment (not that I'm against buying on line, but you really have know what you are doing here, and even the most experienced have problems on line as it is about fit and product knowledge), If you are comfortable you will want to ski more and improve faster.
The advantage of having your own equipment is that is the same and well maintained which again makes it easier for you.
I hope that some of the Supporters and very experience people in this site chime in and give you some more specific advise and product knowledge.
Also read through some of the other posts on this topic, you'll be surprised how many others are asking similar questions.
