What I know about these matters, since I have just deleted the Latest Version of Kazaa a few months ago (and being very happy about that), is that Both Peer Points Manager and P2P Networking are Part of aforementioned program.
-180 solutions search assistant is Spyware as I know a m8 of mine had that program.
-Mysearch Bar IIRC is adware thats packed with MsgPlus for MSN.
-MSXML 4.0 is something I know nothing about, But Komrad Esky saying that its allright would constitute its right to be there.
Ohh, and before I forget, when I used Kazaa, there was another little surprise that D/l'ed itself onto my computer: Perfectnav, This is basicly a search program that acts every time you type the wrong URL or when there is a little glitch in the URL, its Spyware, and if I am not mistaken it has installed itself onto your main drive (Default is the C:\ Drive), I would search for it if I were you, its not only Spyware, it's also Bloody annoying.
Here are the removal instructions.
Just in case its loaded onto your Hdd. WARNING: Part of the Removal instructions tell you that you have to Edit the Registry, As per Tawakalna's advice I suggest you find someone very able with the Registry rather then Do it yourself, its extremely Dangerous, Don't say I didn't warn you about it!!
Also, if things go Awry, I accept no responsibility for it.
