Narrative:

IOE event for PF..me.. Inbound to fnt; RNAV GPS runway 36; had planned for ILS 27 switched to RNAV approach with flint approach. Received late vectors to join approach at cokin intersection; high and fast to begin approach; selected flight level change; speedbrakes fully deployed; speed 240kts; started approach; missed lavs procedure on selecting VNAV; dialed down to 800 feet; LNAV; speed; very busy monitoring radios and course; aircraft intercepted lateral course in a turn to final. Level change took us low; by 200 feet; we recognized it and went autopilot off; added power; speed brake retracted; leveled off and climbed back to altitude. At the same time; flint approach issued a 'low altitude alert'. During this whole event we were in VMC conditions and had the field in sight at 10 miles. Continued visually and executed a normal landing.we were rushed getting everything done for the approach. I also have a total of 15 hours in type; so this approach change at 0500 was difficult. We should had continued with our original plan of ILS 27 and not asked for the RNAV approach. We made ourselves rush into a mistake.
