Paolo, within the request type definition, you can hide fields and specify values - this results in new requests being created with predefined values that you didn't have to obtain from the user. You can read more here - https://confluence.atlassian.com/display/SERVICEDESK/Setting+up+request+types.
You cannot do with configurations. Maybe some javascript hacks might work but I haven't tried it before and so not sure.
If I remember, SD plugin didn't support html in descriptions etc and that will make javascript hacks difficult. You will probably have to inject them in to the correct context via a plugin.
