Details from the email can automatically create incident, change, request etc by linking the mail box to service details.

The Basics is that you setup a mailbox in the Mail component in servicedesk, you create the mail mappings and you link it to a process and maybe a template, but for more in-depth knowledge see the link above.
I wonder if the use of Event Manager would be a little more elegant than an email to a mailbox?
Get your web forms to send a web service call to the event manager service. This would then be picked up and a request (or indeed any ticket type) created. You would be able to specify the service you wish to raise the request against in this way along to with a lot more information that is limited in Mail Manager; mail manager only maps the end user, the email title, body and attachments. Event Manager would allow a lot more control over what information is populated from the web form.
