If you've soldered before, but never on something as small as this connector, grab an old cdrom drive and practice on that first. They have similar connectors on the boards inside (actually...if you're lucky it may have one the same size).
If you're eyes aren't very good (I don't trust mine like I used to) then get one of those big magnifying lenses with the ring light around it, and use that to look at what you're doing. It's amazing how much easier it makes the job when it's magnified so much
