Echo.... boots first...
As for skis - every one of the manufacturers listed makes great skis. In fact, personal preference and snobishness aside - every one of them makes better skis than you could have gotten for virtually any amount of money 5-10 years ago (this is a point made by many people in many places - so I'm not taking credit for it).
Personally, I don't love rental skis. We tried for a while - especially with a bunch of kids. The hassles were not worth it.
I'd suggest any highly rated all-around intermediate to advanced-intermediate "all mountain carver" ski. Something 74-80 mm in the waist and with a radius of about 12-18 meters. Shorter rather than longer... Every major manufacturer has decent skis of this general type. Many to choose from. Very, very carveable, yet will do you well in a broad range of conditions. And will not inhibit your progress. Atomic Izors (yeah, waist is a bit skinnier) or mid-range Metrons, Salomon Scramblers, etc, Elan Magfire 8 (maybe even 10), Rossi Zenith Z5, etc... Or loose eqiuivalents from last year. You could also do worse than some of the versatile twin tips like last year's Salomon 1080's which are actually excellent all around skis as well. In general, avoid "beginner's" skis.
As you will often find others mentioning here - drop a few bucks on www.realskiers.com
and tap into their reviews. Well worth it.
A disclaimer - I have not skied most of the skis I mentioned - just going from specs/reviews. They are all in the general category that will suit your purposes.
