Should the words in bold print be within quotation marks?

They mean different things. Will implies sureness . Would implies a doubt, with the possibility that the speaker could be wrong.

Should the words in bold print be within quotation marks?

Thanks.

I think there is no hard rule here but I would put the words you marked bold in quotation marks to make the sentence easier to read. Let’s see what @Alan and @Andrea think.

I would recommend you either leave the words in bold or use single inverted commas. To use both would be over egging it.
