Descend and maintain 2300 feet, Cleared ILS RWY 04 approach.
This clearance allows you to descend to 2300 FT MSL right away. When you are on a published part of the procedure (i.e. on the localizer with positive course guidance) you can then descend to the altitude shown on the chart for that segment.
You can choose to remain higher to capture the glideslope or descend to the MEAs when allowed.
I am a firm believer in a stabilized approach and staying higher to capture the glideslope helps to accomplish that. There is an issue, however, with capturing the glideslope early and following it down and it has to deal with warm weather. In warmer than standard weather, it is possible to be on the glideslope and find yourself below the MEA for that segment of flight.
In that case, it may be best to descend to the altitudes listed on the chart until you are at final approach fix altitude and then capture the glideslope and descend.
In your specific example, I Would descend to 2300 FT MSL and capture the localizer. I would stay at 2300 FT and descend on the glideslope. In really warm weather, I would be cautious of my altitude crossing LAROD and GOPRU
