Refinishing old wood stairs?

I recently installed laminate flooring. I also removed the carpeting from the stairs. The nose of each stair is rounded and I don’t think I can fit the laminate flooring and the front nose piece that came to finish the stairs over the rounded edge. So, I was thinking I was just sand and stain the existing stairs. I’ve started by removing any staples or nails that were left from the carpet and started by sanding the bottom two stairs. I don’t feel like this approach is going to work. How do I refinish these stairs?!? aahhhh.. Anyone with an eleborate response or step by steps…please email me. cjohnson1104@sbcglobal.net

You will probably have to sand………Or if they have varnish on them…….I would get some paint and varnish remover…You need plenty of ventalation though….then sand them down….put stain on them….let dry really good ,then a coat of polyerthan.
