Several question regard the userpoints usabillity and future to come...

1. Is there a way to add the point's on a user node to his own points "bank"? I will be happy if someone did it and can explain me how to.
   Take a look at userpoints_basic as it is a good basic example of how userpoints work. Points are granted to a user and NOT to a node. They can be granted for anything for any reason IF you write a custom module otherwise you can use any of the methods available in the userpoints contributed modules.

2. Regarding all the userpoints tables. Are this views? cuase I can't find them in the views. If not, How can I manage them differently? For example, The operation section show me "insert" for all of the earning points types, and I would it to actully show the name of the... article, post, comment, etc.

There is a views module that you need to enable before you can see the points, in relation to a user, available to views. If you want to use the default reports you can theme this report using the theme_ functions

1. Seems like several word's arn't in the translate system and I can't change them for my language site.
   Please let us know what these words are.

1. I under that userpoints give points to the user for his actiosns on the site. what I want is to add to this points poll the points given to his article for example, and make a sum out of them all. ovieslly using some voting module.

this is probably what you are looking for. If not you may have to build your own custom module but the main idea of the userpoints module is that it is a core and a foundation. Building a custom module around userpoints is easy and quick.

The second question - I have the views module, ehat I was asking is for a way to change what the userpoints tables include(not the look).

look at userpoints_views.inc if it is not providing what you want.
