Redoing Interior

I'm redoing my interior b/c when my bro had the truck he messed it all up in ways that noone could imagine. So I'm taking everyting out hopefully if all goes to plan. Whats the easiest way to get the dash out w/o breaking anything on a 91 s10. and when i have the dash out im changing the heater core b/c its cracked somewhere. plus i need to get a Temp Gauge! I'ts broken so i gotta replace that lights in the gauge panel. Plus its like hanging on by like 2 screws cause i just pulled it out of place the other day. Thanks for any help!
