We do cover Netsky under signatures 3136-0 to 3136-11 however we do not cover the variant Netsky.aa. If you look at the overall risk rating for TREND for this virus it is low. We partner with trend to cover virus or worms at medium to high severity levels.
Seeing as we partner with TrendMicro for virus and malware, we also happen to use their naming convention. I was able to cross reference some of the list you submitted, coverage as noted below.
That said, the IDS/IPS is a network intrusion sensor, not an antivirus solution. We provide coverage for viris/worms/malware that are fast breaking and pose significant risk to the end customer, but we do not cover every threat out there. For virus/worms/malware that are elevated to a High severity on TrendMicro's site, you'll see a signature on the IDS platform for it.
To my knowledge, there are no plans to incorporate anti-spam filtering on the IDS/IPS platforms at this time. Frankly, it doesn't make much sense to me to have your IDS filter for spam, but that's just my opinion.

Did a quick search on Trend's site, but didn't find a match to these:
