One thing for sure is the tracks with less in them eg two or three parts at most will sound louder even when the meters show the same reading.  That does require a gut feeling.  It is one of the very few things that the meters don't show.  From experience I usually drop them by about 2 to 3 dB.
 
The biggest and loudest biggest track should be the loudest thing on the album. That is why you master it first.  With big loud tracks I might even squeeze another 1 dB out of them  (compared to the average overall level) from the limiter so they have that impact.

so, it may be that in those collection of songs,
there is clearly one that should be the loudest,
and you create the song order, based on building up to the loudest song,
and gently sloping away from it, in order of song.
 
point is, have a strategy

The track order is another whole story. Once the tracks are mastered the order is critical.
 
Here are a few tips:
 
Avoid consecutive tracks that are in the same key if you can.
 
Avoid consecutive tracks that are very similar in tempo and feel.
 
Try as Bats says to create a whole story in terms of what the tracks are all saying and doing one by one.
 
The big number does not have to be two thirds down the line either.  That is a bit old fashioned.  I have mastered CD's where it was second or first even and it still sounded great!  But saving it for a little while isn't bad either.
 
Watch where the quieter tracks are in relation to louder band tracks.  Ensure the quiet tracks dont jump out at you. They can if they are too loud.
 
Sometimes the client really knows and wants the order, sometimes they have some idea and sometimes they don't have a clue and you need to help them.
 
Burn several CD's with different track orders and live with them for a while.  You will soon know the orders that are not good.
