I am not sure I could reproduce this. With local test file, I was able 
to get a fill polygon with external symbol working.
If you have a simple map/data I can use, you can create a trac bug and 
attach it to them and assign it to me (osgeoid: assefa)

I was able to reproduce this. I have added a bug 
(http://trac.osgeo.org/mapserver/ticket/3855) on it and a patch that 
should correct the issue. Is it  possible for you to test the patch and 
report through the bug? Thx

Here again I tried vectir synbols (weel-know sld symbols like star) as 
well as the graphic symbols but could not see a problem. The roration 
parameter should translate into an angle parameter in the style. I have 
tried this using agg output. Here again if you have test data that 
demonstrate it please open a trac bug.

Same as above.

For new features/enhancements, It would also be better to add them in 
trac and mark them as enhancements. They can be addressed for future 
versions > 6.0.
