OK everybody! I'm 50+ hours into this awesome game! To answer some questions. No you can't get more than 1 skill point per level up. So you gotta be careful on where you place them. If you spread them out too thin then you won't get the really really good perks at the end of the chain. Just be careful.
Secondly, whoever mentioned something about the factions not showing themselves. They rarely will come to you. They aren't mandatory to enjoy the story or even essential to the story itself (save for 1 or 2) so you have to kinda look for them. Just ask around to everybody you'll see, you'll find 'em just fine. They all have quest lines (some short, some long) but feel fleshed out and are enjoyable in the end.
Dragons. I've fought many and have found many shouts. Dragons are significantly easier if you have a companion but not required. Obviously ranged attacks (destruction magic and bows) have an advantage but are not the only means of killing it. When it lands you gotta sprint behind it to do the most damage. Not because it is weak there, but because you're more likely to not be attacked right away there. Just my word of advice.
Any other questions just throw them out here. I'll be on to answer for you.
