I have not yet seen any rules for advancing NPC's. (eg: level 3 expert, level 2 commoner, etc). Do such things currently exist or no?
Are there any rules or talk in the PHB of gaining XP in any other way then through killing monsters?
Hiya.
No, I don't think I've seen anything either. I'm primarily posting this as a suggestion to try not thinking in "3e/4e/PF" terms. Thinking like a "0e/1e/BECMI" DM will probably serve you *much* better with the new 5e rule set. What that means, in regards to your topic...is that you don't "advance" an NPC. You create him whole-cloth for exactly what you want him to do. There are no 'rules', no 'advancement', no 'NPC classes', no 'templates', etc. that you simply tack on to a base and add the numbers.
Now, I suspect there will be stuff about NPC's in the DMG, but I seriously doubt there will be anything you might think of as "advancement". I'm guessing that an NPC will basically have a very simplified stat block that has his name, race, sex, age, stats, Proficiency Bonus and skills.
IMHO, this is a GOOD thing! A DM shouldn't spend an hour writing up two innkeepers just to try and have said innkeepers be "appropriately balanced". I've found that the way 5e plays is heavily leaning towards DM's actually doing DM stuff and not bookkeeping stuff. (re: a helluva lot easier to 'wing it' without worrying about stepping on anyones toes or otherwise messing up the system balance).
If you are talking opponent NPC's (re: ones with classes and such, like the PC's)...then just make them as PC's. Feel free to add what you want and take away what you don't. With the more simplified systems, which 5e is, its a lot harder to screw things up beyond repair; ex: take an NPC Fighter with Dueling Style...take his +2 damage away and sub it with +2 to his AC to simulate 'expert parrying'. Done. You won't break anything, I promise. It will make for a memorable NPC and you don't need any sort of template/class/whatever to do it.

Not in the PHB. However, the adventures published show that there is another way: milestones. With milestones, you assign a set xp amount after the PCs have completed a goal or quest.Are there any rules or talk in the PHB of gaining XP in any other way then through killing monsters?
Primarily I was thinking about what used to be the NPC classes like Expert and Warrior and such but, if they don't really exist, that's okay.
I'd be okay with this.Hiya
I suspect the DMG will have "competency level" examples. So we may have a simple stat block for a "Guardsman". There would be, say, four Competency stages for them; "Recruit", "Experienced", "Leader", "Professional". We'd then have "Guardsman - Recruit", "Guardsman - Experienced", etc. Each one would have a slightly updated statblock to reflect his competency level. I think this would be the best way to go. It gives solid 'ranges' for low, medium, high, and very high capabilities, but keeps all the number crunching and fiddling out of the picture. It allows a DM to quickly grab whatever is closest to what he needs, and then easily tweak a bit to fine tune (drop this, add that sort of thing), based on what he needs, without having to go into "statistician mode". It would also likely not take up dozens of fricken pages. Whit I don't want, is a base "Guardsman" and then a half-dozen "templates" that I then have to manually add together to finally get my NPC. If I need an experienced guardsman, I can just use the "Guardsman - Experienced" stat block and go with it...modifying on the fly if needed.
