After running iterations of lm() in R, I am now stuck with which components of the model's output to present and how to present them. I know that the $R^{2}$ value, coefficients plot and intercept are of central importance. Is there any free resource which shows: how to interpret output, and then visually represent of model outputs,especially output from R. I read Interpretation of R's lm() output but I find it difficult to translate that into what it means in my domain.

My domain is marketing. I am trying to model impact of TV advertising on lead generation. My $R^{2}$ value is high but when I plot my coefficients using coefplot in R, they are on the 0 Line. I don't know what to make of it. Happy to share more details & output.

Here is the model output & plots:
