thumbnail pictures

I would like to know if one of the two options below (or both) are possible:

1- full posts to show thumbnail picture on the left and not at the top as they are currently shown (e.g. the theme explanade shows posts like that)

2- When posts are shown on a grid, can they display entry date, author, categories, etc. (if not all of them, at least the entry date would do it)

Thank you
