Need guidance on migrating from Access into CRM

I welcome any guidance you have on migrating MS Access into CRM.

I will need to manipulate / programmatically process the Access data to get it into the correct locations in CRM.

My thought is to import Access into Creator and work from there.

A key question is this: For a given Action applied to Multiple Records, what is the maximum number of records I can select for a single execution of an Action?
