Hiya,
1) I'd import the whole spreadsheet into a temporary table with an additional autonumber primary key field, and then use that to pull all your data. This will definitely help with problems with data-types etc.
2) Design your new tables. I assume that you want to retain each seperate table row's relationship with it's related row in the other tables? If so, you'll need foreign keys to do this.
If you post the full field list in the Excel file, along with the fields in the new tables: I can point you in the right direction for designing the relational tables.
3) One query could do this, but it may be simpler to extract
each table seperately (each time referring to the autonumber in the full data table).
