I'm sure they translate to the Blade too. As everything in sailing also here you have different ways of trim with the same result, but the page is a good base to start from.
If you are new to trimming, I would advise not to try and have everything right from the first time.
I mean start with putting the mastrotation in a fixed position (pointing at the rearbeam when it's windy, pointing at the daggerboard casing when it's not) and don't touch it anymore during sailing.
Then start to use the downhaul. A good rule here is that you should be able to cope with gusts/lulls with only an armlength of mainsheet (standard purchase). If not you should adjust it.
Concerning the main, I almost always sheet in as hard as I can (except when in light to moderate winds -> 1 trapping max, where you need to ease just a little to get the tell tales flowing).
I never let the traveller out (sailing 2-up). Normally the sail should flatten enough.
And I only pull the boards up in heavy seas or very gusty wheater. Otherwise I don't have the feeling it makes much difference.
And although Matt doesn't have a trimsheet on his site, he has always answerred me if I had specific questions concerning the Blade.
