Fortunately there are lots of skis out there that will work well for what you're looking for!
First I'll start with boots. You're going to want to go see a boot fitter most likely. If you're planning on investing in gear that you're going to keep for a while, take the time to try on multiple boots in different styles and widths. Since this sounds like your first time buying gear, I would recommend going to see a professional boot fitter. If you're anywhere near Stowe, VT, Benny at Inner Bootworks does great work.
As far as skis I would point you towards something in the mid 80mm under foot range. I would stay away from skis that use metal in their construction, as at your weight and ability level it's going to hinder progression. I would also recommend getting into a ski that has some subtle tip rocker. This will help your turn initiation as well as increase stability in soft snow and help "pivot" the skis in moguls.
Some skis that come to mind are:
Blizzard Black Peal
Rossignol Temptation 88
Rossignol Temptation 84
There are definitely other skis on the market that would work, and some might recommend going with a narrower, lighter ski. I think any one of those 5 skis is easy enough to maneuver and in the long run will help promote progression, while giving you a confident, stable feeling.
