On your first stamp: quick answer, you have a stamp from a booklet pane, Scott 498.
Longer answer: the Scott catalog is not at all clear about identifying these. You are on the right track to notice the difference in width. The dampened paper for the booklet stamps is turned 90 degrees from the sheet-stamp stock when run through the press on these early issues, so the grain of the paper runs "the other way" for booklet stamps. When dried, the paper shrinks back to its original dimensions - shrinking at a different rate with the grain versus across the grain, leaving booklet stamps slightly shorter and wider than the sheet stamps of the same Scott number.

Second stamp: There is no way to tell anything without some comparison item in the scan. Please search for threads about making overlay "templates" from known flat/rotary stamps. Also, scans of the back side are very helpful to ID'ing these issues.
