Would something like this help?  Scroll down a ways.

  Cool.  When I merged them all it took my a couple of tries because I would skip just one little step and have to start all over.  I did enjoy mixing everybody around, though.  Brandi and one of the Curious brothers ended up very happy together.

  Have you checked Club Crimsyn?

 I do believe that these may help. 

  I would keep an eye out at Garden of Shadows.  They have quite a selection of recolors and re-textures of Peggy's hairs as well as others.

  I did see the Peggy 5054 there, but it is a female to male conversion.  http://www.digitalperversion.net/gardenofshadows/index.php?topic=11641.0    Not quite what you want, but maybe keep checking. 


  Now pardon me while I go snag the original to test it in-game.

  Something like that you may have to merge them yourself.  http://www.moreawesomethanyou.com/smf/index.php/topic,4480.0.html 
 
  Instead of using the empty templates, use the "cleaned" templates.  When I did my own merge, I used Strangetown as the base and added all the rest as shopping districts.  Since you only want one added it shouldn't be nearly as complicated.  You just have the replace a few names and numbers in the directions and follow closely. 

 Oh, and empty templates only work if you put them in before restarting (delete The Sims 2 folder in My Documents - EA Games).

  Have you tried empty templates?  http://www.moreawesomethanyou.com/smf/index.php/topic,13382.0.html

  The link also explains how to do this with just a userstartup cheat.  That is the part that you might want to read more about.

 The mesh is included there as well as http://rissa-styles.tevalon.de/content/blogcategory/16/53/1/14/.

  I remembered seeing a re-texture on GOS.  http://www.digitalperversion.net/gardenofshadows/index.php?topic=9168.0

  For your second request have you tried the Wardrobe Wrangler?  http://www.djssims.com/index.php?category=1&subcat=5

  You are not the only one.  I've been trying for at least a week or two.  What mesh are you missing maybe I have it?
