Few doubts on Services (Components section)

Hi all!
I'm choosing the components to remove from my cd (Win XP Pro) and in the services section there are 3 which I don't know whether taking out.
First, a red component, HTTP SSL: considering that I'm not going to use Internet Explorer, is it safe to remove it even if I use SSL for e-mail or other services?
Second, another red component, SNMP: there is a generic reference to printer support and agents that monitor the activity in network devices and report to the network console workstation. Does it have something to do with router connection, USB devices for connecting to the local router or stuff like that? If wireless printing support (or USB printing) is needed, can SNMP be safely removed anyway?
Third, a black component, Network DDE: does its removal affect the local router connection and security issues?
Fourth, another black component, QoS RSVP (and related QoS): does it have something to do with internet USB keys (such as dLink) for router connection (or HSDPA connection)? If so, should I keep it?

Following the full list of components in Services section:

Lastly, this is my list of components to remove: Alerter, Application Layer Gateway, Distributed Link Tracking Client, Error Reporting, IMAPI CD burning com services, Indexing Services, Messenger, QoS RSVP, Remote Registry, Removable Storage, Service Advertising Protocol, TCP/IP NetBIOS Helper, Telnet, Text Services Framework, Volume Shadow Copy.
Since I use a router connection (sometimes a HSDPA key), do you think that removal of any of the components of my list would badly affect my internet connection?

Do you think I could include something else on my components list, something absolutely unuseful that I missed at first sight?
