I'm also pretty new to brewing but I believe you'll be fine. I left my first couple of beers in the primary for 4wks and 5wks and had no problems. I had very little yeast when bottled.
After 2 wks in the bottle, my beer wasn't fully carbonated. I gave it another week in the bottle, then refridgerated for a week and it was great. It took some patience, but it definitely paid off.
