1) Yes, but technically this is standard NT functionality. Add AutoPartition=1 under the section [Data] to your winnt.sif to auto partition the drive. Add Repartition=No under the section [unattended] to kill all partitions on the primary drive and have it NTFS formatted. 1A) No. The above options will always use the primary bootdrive (IDE0/SATA0), unless some other drive is configured as the bootdrive in the BIOS. 2) No, since the above options will kill all partitions that are available on the primary drive. If you want to select a Quick or Full format manually, you can't use the Autopartition=1 option. Unfortunally, NT's partitioning options are quite limited...
