My 1099-B has only boxes 1a,1c & 1d with info. Do I need to send the IRS, by mail, copies of the purchase & sales statements?

No, you do not need to send copies of the purchase and sales statements to the IRS, even though your purchase date and cost basis were not included in Boxes 1b & 1e. 

However, be sure to keep this documentation in a safe place so that you will have it available in the unlikely event that the IRS requests it in the future.
