aurora instrument panel problem

help.. my instrument panel on my 95 aurora has gone crazy. started with the warning lights flashing all the time. the cruise light stays on all the time, now the gauges go crazy and sometimes do not work at all. lately the drivers control panel keeps flashing and beeping different warnings ( they are not legit, have checked)

another problem lately is that i have trouble starting, replaced spark plugs but still have problem. feels like it is missing when accelerating. this car has been maintained very well, but cannot figure these out. please help
