I think you can probably do it, unless you have shaking hands. I mean, xbox's were the first thing I had ever soldered.

Most chips are the same in a sense that they all have the same objective. Direct boot of backups and unsigned code. However, more expensive chips have things like custom OS's, options for display screens, many many bios banks, etc... Things that are nice to have, but really arrn't needed at all. Which bios you have running on the chips make more of a difference.

Any chip compatible with 1.6 xbox's should be fine. They basically all use the same solder points (except older chips not designed for 1.6 xbox's. THey have editional wires to bridge specific points). I would recommend the x3's simply because I am familiar with all chips that they have made in the past and are all great. However, other people here are just as familiar with other modchips.
