View MX2 provides both the transfer and browsing. It's in the box but by the time the camera gets to you, it's likely to be out of date. View NX2 is a free download from Nikon's Web sites, get it there instead.
I don't have any experience with Light Room, but based on what I've read and heard from others it's a very good program. I expect LR's learning curve is less than learning Photoshop.
I use Photo Mechanic for input and browsing and Capture NX2 for editing and printing.
