I'll give my answer to this below

I'm not sure of how to rebind it and very rarely use it, but standard
binding has this:

      j and J
           Cycle through the available subtitles.
      y and g
           Step forward/backward in the subtitle list.

Do the y/g ones work for you?

As for the playback position thing:

I started to use "touch NNN" where NNN is the seconds through playback
shown in the output, eg "30" (rounding down from 30.5) here:

V:  30.5   0/  0 43% 39%  0.0% 0 0 

Then I'd use "mplayer -ss NNN ..." with tab complete helping me.
Eventually that evolved in a full on shell script.

I've included the script below for anyone interested. Written for ksh, 
bash should work instead.

#!/bin/ksh
# mplayer wrapper for movies
#
# Should need no args, but any can be passed through to
# mplayer. An explicit '-ss N' will override a bookmark
# file, but a 'restart' file overrides everything.
#
# A useful arg: -vf screenshot  then use 's' to screenshot
#
# Semi-Automatic bookmark:
#    If there is a file of two to five digits in the
#    current directory, use that as a starting point
#    (100: one minute forty seconds; 10000: two hours
#    forty-six minutes forty seconds). This format bookmark
#    is easy to use with mplayer. When you quit mplayer,
#    the last few lines of output look like:
#   
#      V: 811.2   0/  0 70%  4%  0.0% 0 0 
#    
#      Exiting... (Quit)
#   
#    So, "touch 800" or "touch 811" would be a good bookmark.
#    If multiple such files exist, which one gets used is
#    indeterminate.
#
