upgrade issues on blog

Hi Sakin, I have a "subscribe to blog" widget which I want on the blog page. I see that you have extra widget areas which I can use. I want this widget to appear on the first page of the blog (archive page or summary), but right now its showing up on each blog post.  How can I get this on the "archive page" as well?  Which widget area do you suggest? Other things I would like to correct - the first page of the blog has "Blog Archives" at the top before the posts, don't know where this came from as it was not on the original.  How can I get rid of this or change this to another name i.e. Recent Posts? Also on this page, I would like to run the sharing icons right across the post summaries at the bottom of each post (under the pic as well as copy). Right now they run across the bottom of the copy.  I would like the icons to follow the line - I am using the "sharing" in Jetpack for the icons. Thanking you for you help. Karin
