I would like to create a ranger with some Scout or Hunter powers, but I don't know if it's possible.
Furthermore, when reading the Scout description, at first level I find a column with the class features and the powers, but I can't distinguish them from each other.
Which are the Scout's class features and which are the Scout's powers?

Yes, it's possible to select Scout or Hunter powers if they have a specified level.
As a general rule, when a member of a class is eligible to select:
and a level is specified, he can select a power of the same type and of lower or equal level from any homonymous class.
So, for example, a Player's Handbook 1 Ranger may select Speed of the ZephyrDDI (described as Ranger Utility 22) upon reaching 22nd level.
A 1st Mage Wizard from Heroes of the Fallen Lands may select Thunderwave (a Wizard At-Will Attack 1) from Player's Handbook 1 and vice versa.
A Player's Handbook 1 Paladin cannot select Righteous Radiance as one of its powers at 1st level (because that power is described as a Paladin Attack). He can however, select the Strike of Hope power (because it is described as a Paladin Attack 1, that is: it has a level).
Those listed in the class shaded box are all class features.
Some class features are expressed as powers (in fact, they provide powers). Other powers are taken with the character normal advancement. I think you are interested into telling the difference between these two.
Most Player's Handbook 1, 2 and 3 classes share the same advancement in power selection (called AEDU). AEDU stands for At-will/Encounter/Daily/Utilities. All have they unique class features gained at 1st level, but then, they all gain powers at the same pace (as you could find out on a big table in PH1).
Heroes of Fallen Lands and Heroes of Forgotten Kingdoms classes (as well as other subsequent classes) exited the AEDU paradigm by providing another approach. Class features are granted throughout the whole career, and occasionally you select powers from a list, so the difference between a class feature and a vanilla power has thinned.
However, if the distinction is important for you, you have some clues when deciding if something listed in the class breakout is a class feature or a vanilla power.
Examples:
This is also a clue to when a power derives from a class feature: if it hasn't a level, chances are that it is provided by a class feature or feat.
