The key is to do things gently at first so you can feel out where it's catching before trying to just rip the trim off (and break something!)
Remove the centre console and gear shifter too - it'll help when you need to roll the dash rearward towards you and reduce the risk of damage. You need to remove the centre console trim anyway to get access to the bolts holding the dash centre support rods to the tunnel. To get that centre console trim off, you need to take the gearknob off the shifter, which goes back to my earlier comment about removing the shifter. The last thing you want is the thread on the top of the shifter gouging the top of your dash.
You'll also need to take the lower speaker covers off on either side of the dash so expose the 2x bolts holding the lower part of the dash assembly to the sheet-metal.
When you get the cluster out, you'll see the white mechanical speedo drive end clipped into the dash, with 2x big male electrical connectors. Disengage these from the dash plastic, otherwise you'll run the risk of damaging your wire harness when you try and wrestle the dash away. It'll also help getting them off when the dash is still in position, rather than trying to manage when it's half in/half out where it should be sitting. The mechanical speedo clip is a little tricky to get off, but just be patient and carefully work your way around it.
