1) No, the speaker does not feel that he has made the wrong decision by taking the road less traveled. He says that doing so has made all the difference. The speaker sighs because he knows he has accomplished something by taking the road less traveled by. His regret is only that he could not take both roads and was made to choose.
2) A choice between two roads that seem very much alike will make such a big difference many years later because that decision, that path, will open up different opportunities in the future. The one he picks now will influence the rest of the decisions in his life because while the two roads seem alike right now they branch out with different options. Some of those might ultimately be the same, but there's guaranteed to be at least a few different choices on each road.
The Road Not Taken is about a person who comes upon a big decision in his life and has to choose what he's going to do (which road to take). He thinks through the first decision (looked down one as far as I could ln. 4), then thinks through the other option. He decides to go the direction most people wouldn't have taken (it was grassy and wanted wear ln. 8), but if ever he finds himself in that situation again he says he'll try the other option (I kept the first for another day ln. 13), though he doesn't believe he'll ever be faced with that decision again (yet knowing...come back ln. 14-15). At the end the author sighs; it's not a sigh of despair but one of achievement. He seems to be very pleased with the decision he made and the path it has opened up to be (I took...the difference).
