always check the comments in the viewhelper file! you can find the files
in EXT:fluid/classes/ViewHelpers/
Example
---------
 *   <f:for each="{0:1, 1:2, 2:3, 3:4}" as="foo" iteration="fooIterator">
 *     <li>Index: {fooIterator.index} Cycle: {fooIterator.cycle} Total:
{fooIterator.total}{f:if(condition: fooIterator.isEven, then: '
Even')}{f:if(condition: fooIterator.isOdd, then: '
Odd')}{f:if(condition: fooIterator.isFirst, then: '
First')}{f:if(condition: fooIterator.isLast, then: ' Last')}</li>
 *   </f:for>
---------

so you can use {fooIterator.isLast} to check if it is the last one

If you want tags, you got a Tag Model and you need a Tag Repository.
