The Lowers aren't horrible for a newb but the climbing (though easy) can be a little awkward. It is the easiest to walk to though. The colored routes and the numbered balance climb routes on the main face are much more straightforward for both a newbie and a teacher. Multi pitch trad is stretching it a bit, though there are routes where you can do it (Balance Climb 9). There's a lot of routes on the Main Face where you can easily lead up to the Army Cable or just follow it up from the ground and set up a top rope. I've seen a lot of first timers on the colored routes and the balance climbs.
