A few of those errors can be fixed by replacing the & with &

And <embed> is a one sided tag so it should end like <embed /> not <embed></embed>. Not sure about the attributes for embed tho.

I think keeping to standards is a good thing and can help you in the long run in terms of future proofing, but I wouldn't be too worried, your errors certainly don't seem that severe.
