"Information" = uncountable noun but...

Hello,
I´ve got a problem with the word "information".
I know that it´s only used in singular. To refer to the plural I have to say: pieces of information. Now my question: In case I want to express the plural do I have to use the plural verb form or the singular verb form?
For example: "We sometimes get information which are really unnecessary." Right or wrong? What about that sentence: These information are a blessing or a curse. Right or wrong?
I´m getting confused. Is it the same as with "news" ? This news is good (referring to the plural)

Please, help me!!!

Thanx a lot,
Sandra.

"We sometimes get information which are really unnecessary." Right or wrong? Should be: We sometimes get information which is really unnecessary.


These information are a blessing or a curse.
Should read: This information is a blessing or a curse.

"News" is the same, always used as a singular word. :-)
