Most distros that I'm familiar with have the ~/.bash_profile default to 
source ~/.bashrc , and then put the interesting code (like colorising 
'ls') into the '.bashrc'.  That might be simpler.  It makes it more 
difficult to have non-login-shell only code, but I am not sure what that 
would be good for.  (Separately from "login"ness, you can check for 
"interactiveness", e.g.
case "$-" in
   *i*)    echo This shell is interactive ;;
   *)      echo This shell is not interactive ;;
