I got a DTM myself. Personally the oil will depend on what sort of service plan you going to use. If you plan to service it yearly I will strongly recommend mobil 1 0w40 as you suggested.
The 5w30 edge that scotty76 suggested can be used as well but is generally used for cars on a long life service plan.
But from personal experience the Mobil 1 0w40 is a incredible oil. It does the chain and oil pressure a lot of justice especially for early morning or just generally cold starts.
I know it retails for around £50 from halfrauds but if you have a costco card or a friend with one get him to get it for you as its only £29 or £29.99.
Xenon was a optional extra. Thankfully mine has them
And just to comment on everyone talking about the grill. It is actually in piano black so it quite shiny which i don't think is the same as the SE which is a matt grey or matt black finish.
