Stripping source style & image sizes

Hello Allen

Thanks for this wonderful plugin. I’m using Feed to Post option and have two issues.
1. One of the source sites has it’s paragraphs italicized, and that styling carries over to my site. How can I stop that from happening?(I would like to get rid of only italics; and keep <p> tags if feasible

2. I chose unrestricted image sizes option. However, instead of the original size being displayed, the images width is always sized to 900px. I would love for an original size to be showed or at least set min/max width.
