Serious advice to our readers: Buy the Ritter pack (see ETS Home page)(Top right on this page) and add a AMK bivvy bag or blanket.
I'll leave the knive choice to the reader.
Absolutely!
You also need to make informed choices about how to obtain drinking water.
I also recommend that you augment that kit with the Doug Ritter mk5 knife as a backup to your main knife. That way you always have a reliable knife even if your main knife is lost, unsuitable for your present company or left at home for other reasons.
