I would also suggest using a face primer before foundation. It'll help it stay on all day (and night!), and will even out your skin tone. It will also make the pores les visible. The best one apparently is Smashbox Photofinish. I bought one by Gosh (the Superdrug exclusive brand) that is very similar, and I swear by it!
Using an eye primer is also a must, to avoid your eyeshadow creasing or fading. My favourite is Urban Decay eye Potion.
It's a good investment, as it lasts for ages too!
If you want to try out mineral foundations, Lily lolo (UK based) does samples for 99p. Also Everyday minerals (USA based) does a free samples pack where you get 4 little tubs of foundation, concealer and blush. Only pay shipping! I got mine yesterday, so can't comment on how good they are, but the blush is lovely and you only need very little.
I would also advise to go book a free make-over at your nearest dpeartment store. You get to try out a different look, and you'll get freebies to try at home. A lot of good brands do them, like EA, Benefits, Mac....
Oh, and congratulations!!! :O)
