The rest of the pages that printed were most likely worksheets, and should not be included with your amended return.
Do make sure that you keep a copy of everything that you send for your records. It is also a good idea to use a service that provides delivery confirmation (certified mail with return receipt, priority mail, UPS, or any other service that provides tracking).
Please note that 1040-X cannot be e-filed - you will need to mail a paper return. It takes the IRS at least 2 - 3 months (and sometime up to 6 months) to process amended returns. Also, depending on whether the changes affect your numbers, you may also be required to file an amended return with your state.
