Is there an easy way to change the settings for alarms 1 and 2?

If you register the A1 and A2 parameters (for setting alarms 1 and 2) to the select screen, you can display the alarm 1 and 2 settings simply by pressing the DISPLAY key repeatedly. Set the CS1 and CS2 select screen parameters to "2504" and "2505", respectively (2504 and 2505 are the D register numbers).
