You can expect a reply from EllisLab within 24 hours. Responses aren’t always immediate, as they’re busy supporting tons of us users out there. Just be patient and they’ll get back to you.

I think I can help you with number 1, though.

The category URL trigger only works on the Channel Entries tag, not the Channel Categories tag.

The Channel Categories tag is actually meant for listing out categories assigned to a given channel, not for accessing information about the category in the URL.

You could use the Category Heading tag pair to access the currently viewed category.

{exp:channel:category_heading}{/exp:channel:category_heading}

That would work just like you’re trying to use the Channel Categories tag now.

I personally tend to use a third party add-on for this purpose. Low Seg2Cat is a free extension that, once installed, allows you to access category information easily, based on the URL segments.

Hope that helps.

And just quickly searching around, I found the answer for the second part of your request.

The Channel Entries tag has a category_request conditional variable, which you can use to determine if a category is filtering the results of the Channel Entries tag.

You can view information about the variable in the user guide.

Basically, your code will look something like this:

{exp:channel:entries channel="project"}
     {if category_request} 
          {categories}{category_name}{/categories}
     {/if}
{/exp:channel:entries}

thanks for reply it worked very well
