the basic thing i do is;
first dynamics processing, make sure you got a solid audio file,
after the compression and stuff i use EQ,
after that i can mess with FX
but of course you can just do it in any order,,,,
remember that lots of compression can take the 'life' out of your audio track,
so if you first use reverb, then i think the sound will be a bit weaker,
less strong, not very natural
so in general, compress first,
and if you more want some sort of special effect, then you can add more compression after the reverb....
just my 2 cents...
