You can go to a 245/70R17 since it's just a slight increase in the sidewall and an even slighter increase in the width, there shouldn't be any issues other than a 2-3% difference in the speedo/odometer reading which will come around after the tires wear down some.
Brand and models of tires to suggest would depend on what you're looking for.
Do you want an all terrain for looks or going off road? Do you just want a good street tire? Do you want something that wears well and will last 100,000 miles? Do you want a quiet tire? Do you want really good wet traction? Do you need snow going ability or you will have dedicated winter tires?
I'd say a good starting point is generally the Michelin LTX M/S. I like them for everything, they wear like iron, have great road manners, have the best ride of any tire on the market, and are pretty decent off-road as well. They are a great tire for rain and snow, though the hard long-wearing compound is somewhat of a compromise when it comes to snow and cold weather traction compared to softer winter-specific tires.
They are available in 245/65R17, and the 245/70R17 size is available in the new "LTX M/S 2" version...which actually costs less. Not an LT rated tire if that's what you're looking for, though.
I'd also suggest the Michelin Cross-Terrain SUV, it's a great tire for a 2WD SUV.
If you were looking to spend a little less, or maybe get a more rugged looking All-Terrain tire, the Yokohama Geolandar A/T-S is worth checking out. They make both the 245/65 and 245/70 sizes, though the 245/65 is H speed rated, much higher than the R speed rating of the 245/70. They are priced really good for tires of that size, tirerack.com shows ~$130/ea, which is really good. They also have tons of other 17" sizes, from 255/65R17 and even a 245/75R17. Overall an awesome A/T at a heck of a price for the size.
