Landing environment
-Approach lights ON
-Runway lights ON
-Landing lights ON

Planning "Do-Lists"
--For just about every phase of flight - including preflight.

Airports - Review in AFD, AOPA Diagrams, Approach plates, Departure Procedures, SIDS, STARS
Weather -
Options - (Go, NoGo, Go Elsewhere, Go another route)
Notams -
Route and altitude -

Airplane - Certified IFR for approaches, runway length, etc
Weight and Balance - .
Alternates - IFR alternate required (123 rule)? If so, which one...Plan - Plan and file...
Airways, Highways or Direct -

Especially flying IFR the NOTAMS are critical. There may be navaids that are INOP, approach minimums that have changed (FDC NOTAMs) and frequency changes.
