post formatting

I am atempting to format my blog as per the image below.

Sample layout

I was wondering if it is possible to wrap the post title, date, post text and, comments text in one div tag and the image in another so I can control the post text separately from the image?

Any help would be great, I am new to this stuff.

this is what I have so far
