Hi Veronica - and congratulations from us as well!
I've got a black One with the chrome pack, chrome mirrors and 16" 5-star alloys:
I would recommend the salt pack, but the rev counter (aftermarket) is £115 and I replaced my Salt-pack carpet mats with the rubber ones (£25).
I went for the salt pack but kept the anthracite interior - i reckon it works a lot better with the black exterior.
The Boost+CD is fantastic (although can be prone to jumping on some roads due to the sportiness of the standard suspension!).
I would also recommend upgrading to a leather steering wheel - much nicer than the plastic one!
All the best of luck and enjoy it!
