Black N82 Housing Cover Replacement: Advice Needed

My N82 is the warm titanium version and I've been meaning to change its housing since the announcement of the Black N82. I was holding back about doing this due to a lot of reasons. First, Nokia care centers here do not offer this service. Video and pdf guides came out but I didn't want to take the risk of breaking my phone if I do it by myself. Second, I did not really need it as my casing was as good as new. And lastly, when I saw a black N82 in real life, I was not really impressed by the looks. It was not as sexy as I expected, which led me to the thought that the silver / titanium color looks better and unique.

But now, I think it's time to replace the entire housing cover. My phone looks really ugly already. It has a lot of scratches, all sorts from thin, lengthy and the most annoying, the deep cuts which are very visible as they revealed black marks. The lower part of the front face plate has its silver finish peeling off, just a little which looks rust at first glance. Not to mention the creaking sounds.

Btw, these results are not very surprising. For 9 months, I can't remember how many times I dropped this trusty device and how frequent it has encountered accidental bumps against rough walls.

A few weeks before, Mike asked for help about replacing his LCD screen cover and he was able to get a lot of great resources from our readers. Everyone has been so helpful so I thought I'd consult you guys as well before I finally plunge into this.

Any tips will be highly appreciated, the best buy, guidelines, warnings, and the like. Has anyone tried this before, or planning to replace theirs as well? I would love my phone to have a new look for Christmas, :)
