When you say you've bought "all the gear" - what exactly do you mean ?
ski suit, socks, thermal layers top and bottom, gloves / mittens, inner gloves, crash helmet / hat ? Don't bother with ski boots and skis - rent these in the resort. If you have never skied before or only once you won't know how boots feel / fit when you're actually skiing so best get them there so you can take them back if they don't feel right
Are you going on a package so that transfers are sorted ? If you're driving yourselves are you familiar with snow chains ?
Booking lessons - ask for recommendations, eg trip adviser / friends / the hotel. Please don't think you'll be able to teach your DH with one week under your belt. be prepared for separate lessons as he's a complete beginner. Get morning lessons, so you can practise in the afternoons. The temptation to go out later in the mornings with afternoon lessons would be too great for me! If you're thinking of a private instructor for the 2 of you - again - it might be best to split the time a bit. I'd be tempted to wait until you are there and take advice from the ski school on which lift pass you will need. Beginners won't necessarily need the full area pass
Before you go - get as fit as you can - it's bloody tiring getting up of the ground all the time. Be prepared for the 2nd and 3rd day stiffness. If your hotel has a spa (and many do in Italy) book a massage and use the jacuzzi for those sore muscles.
Just how far is the hotel from the main resort area ? Does their transport run into the evening so you can go into the village / town of an evening ?
Make sure your holiday insurance covers ski-ing and mountain evacuation - the Ski Club of GB does a good one.
Can't think of anything else just now, but that's plenty to be thinking about.
Have fun!
