Don't worry about sdconfig for now. You can manually run sashimi using the file explorer. I don't know PHreg. If they are being exported to a reg file, you can just put them in the auto\reg folder. Voicemail password is not needed if you dail voicemail from phone - most carriers use caller id to recognize your phone.
Yes, Makisu is what you can use for email settings. I don't know how it works with various mail servers. I use it for pop mail.
