Those are fine. Actually, probably more expensive than needed.
My one concern would be that as a beginner, it might be better to have bibs (overalls) in the way of ski pants. With those pants you are looking at, you may be getting some snow inside there...but that is just a minor concern.
Most importantly:
1) Get a beginners lesson. The price you pay will be well worth it in the long run. I used to instruct. Trust me. Don't learn by a friend, and don't try to do it on your own. It's not like basketball or something. There is a very specific sequence that instructors go through with beginners to start them out on the right foot. All you need is one lesson, and you should be good to go for the rest of the day.
2) Wear comfortable clothes, dress in layers, and wear mitts or gloves. During the first part of your lesson, you will be doing quite a bit of walking around and hiking, and you will overheat in that jacket. So I suggest wearing a good thermal undershirt (NO COTTON - cotton retains all that sweat, and you will be cold and miserable), perhaps a turtleneck, and if you are going to be in a cold place, a sweater as well, all under your jacket. If you get hot, you can shed as many layers as you like. For under the ski pants, probably some long thermal underwear will do. Also, one pair of quality, thin socks. Thick socks, or multiple layers of thin socks tend to either bunch up, or cut off circulation to your feet, and become very uncomfortable. I have known skiers that even went barefoot...a little nasty, but really, if your feet get cold, then the boots are lousy. Feet shouldn't get cold unless you are up in the northeast somewhere in the middle of a 30 below wind chill day.
A hat (or helmet), and gloves (or mitts). Gloves are very important, for a couple reasons. First, your hands will stay warm, and secondly, snow is sharp (ice crystals). When people fall and their bare skin comes in contact with snow, often times that snow will cut the skin...kind of puts a damper on the day. I never liked to teach people without gloves. I always made them go find some somewhere if possible.
Have fun! Skiing is my favorite activity. Been doing this for 30 years now...and hope to never stop!
