Push rudders over gently but firmly; and not quite all the way; if you do; you will stall the boat. 
 
Tiller over; as the boat goes head-to ease about a foot of sheet as you need to re-attach the flow when the battens pop.  As you return to the new heading; sheet back in and out you go; if you do stall; back the rudders and reverse out. 
 
Remember you cannot spin on a pin-head and if windy you will go into the tack at 10+ kts (hopefully) and so it will take a little time to get going again.

Maybe off a bit down wind when howling
 
Upwind; once everything else is tighter than everything else and still over powered let the traveller out a little bit!   Take care with the outhaul (I leave mine and use DH on my F16 but I have a 32:1 downhaul).  If you tightend the outhaul too much then you cannot put enough DH on (or you over tension the foot).

ok; first things first; ask who ever you are borrowing the boat from for the basic setups for Light / Medium and strong wind.  Prebend; rig tension and rake.
 
Unlike Mono's cats sail fastest heeled on one hull (aim for windward hull skimming just above the water).
 
Unlike Mono's we trim the rig slightly differently..we have rotating masts for one thing. 
 
Medium winds you want the mast spanner pointing at the dagger board case (check for exact position); Enough downhaul to remove creases untill both fully trapped out; as wind goes up; add more DH until you cannot get any more on.  Plates fully down
 
Light winds a little more DH and less rotation to keep air flow attached to a flatter sail; Plates fully down.
 
Windy: add  more DH until you cannot get any more and then maybe ease the tarveller a little; I think the Spit still has only 8:1 so when I say max DH give it plenty of welly! then think about also pulling in the rotation in a little more (till it's pointing at the outboard end of the back beam.   Plates up around 50cm (check). 
 
That's the basic upwind trim;
 
Downwind; plates up most of the time (check).
 
Drive for speed and then for angle; there is plenty of power; use it!  If wiring up wind; crew may well need to be wiring down wind!  Fly a hull until it gets silly windy. 
 
Even in light wind speed is still important; but it takes time to know when to go from hunting speed (and so pressure and thus fly the hull) vs taking gusts deep.
 
This is going to feel very odd probably; the apparent drives forward so quickly that as soon as you have some speed; wind SPEED is more important than angle; best bet is to usually take then gust; get speed (and thus pressure and thus can bear off) and then think about gybing if it's a lift, but a 8 second gybe takes a lot of distance at 15+kts. 
 
Now; who does what??
 
It may pay to give the crew the mainsheet upwind (and you take the DH); crew is responsible for "ride height" and you for direction and tacktics; remember cats do not tack on every shift; we have to take strategic decisions; not simple shift->tack reactions.   
 
Roundings; work out who does what; you might be able to raise the windward plate while the crew pops the kite; maybe not; 
 
Downwind gusts; Don't dump the mainsheet; that breaks the mast; You MIGHT get away with dumping the traveller in those dive-dive-dive momets!
 
Where are you going to be sailing; the fleet will help out - they are mosly harmless!
 
Oh; and have fun!!

Loads; I've trained a few in 30 years of sailing cats!   (and I know how important a good one is, and how it makes sailing cats different).

Matt
think the biggest thing is dont bear away in a gust unless under kite, has the opposite effect to what you want and you will get wet
