You don`t have to follow the first 2 links because Win Vista and Win7 can make the partition perfect itself.
After a clean install of Win7 you can use TRIM without install Intel`s SSD Optimiser software.
If you use Win Vista you have to use Intel`s SSD Optimiser software to make TRIM working.

"After a clean install of Win7 you can use TRIM without install Intel`s SSD Optimiser software."
Do you have a reference supporting that comment?

Yes, I`ve reference http://www.anandtech.com/storage/showdoc.aspx?i=3667&p=3 here. In the first article.
"Your best bet is to install Windows 7 with your I/O controller in AHCI mode (for Intel chipsets) and don't install any storage drivers."

Your reference is discussing "passing the TRIM instruction to SSDs".
That is only part of the the process.
From: intel_ssd_toolbox_fqa.pdf
"The Intel SSD Optimizer is the tool that implements Trim functionality."
