These filters will modify the quick reply code to add checkboxes for automatically parsing URLs, and disabling smilies in that post. it also adds the ability to change the text on the quick reply button, so you don't need a seperate filter for that.
I made a small change to the filter submitted by Dagatech. I couldn't stand the font-tags so I removed them in favor for span tags ;)
URL = "www.genmay.net"
Active = TRUE
Limit = 4096
Match = "(<input type="image" src="images/smilies/spam.gif" style="background-color:transparent" class="bginput" name="submit" value="" accesskey="s" tabindex="2">)\3"
Replace = "</td><td><input type="checkbox" name="parseurl" value="yes" CHECKED> <span style=\"font-size:8pt; font-family:arial;\">Automatically parse URLs</span><br>"
"<input type="checkbox" name="disablesmilies" value="yes" > <span style=\"font-size:8pt; font-family:arial;\">Disable Smilies in This Post</span><br><br>"
"<input type="submit" class="bginput" name="submit" value="BUTTON TEXT HERE" accesskey="s" tabindex="2">"
