This is a job for optionSplit:
http://typo3.org/documentation/document-library/references/doc_core_tsref/4.1.0/view/3/1/#id3520928

According to the TSref you should change your code to look like this:
# Normal state properties
NO.allWrap = <li> | </li>|*||*|<li class="last"> | </li>

# Enable active state and set properties:
ACT = 1
ACT.allWrap = <li class="act"> | </li>|*||*|<li class="act_last"> | </li>

you don't need the "topMenu" in the class of the <li> since you could use 
<ul class="topMenu"> and then do a proper cascading.
