Title and Tags for multi-language enviroment

Dear All.
First off I want to thank you for the help received sofar. I am very pleased with you effecienty and your quick response :-)

Now I have another issue...
It has to do with the same web I asked yesterday about and to which Arlex very professionaly helped me out.
the web is: http://v2.tantramassagehotel.net/index.php/en/blog
Basiclly I have 2 issues:
1. when you go to this web and you change the language you´ll see that the title of the web is:
Bienvenido a nuestro Blog
Periódicamente publicaremos aquí las ultimas novedades
Now when you switch between languages you´ll see that this title remains in spanish.
Is there a way I can have THIS title for the spanish version and THIS title for the enlish version?
Welcome to our Blog.
Check out our blog. We will frecuently post on our blog our latest news.
How go I about to have the title in two (2) languages, is this possible?

2. Same things happens with the tags module
I would like to load in sidebar-a position the module with the english tags and switching back to spanish I would like to show the spanish tags.
How go I about this to acomplish this?
Is there maybe a way I can filter the tags using the Joomla Tags? Because I saw that the Joomla Tags allow me to create a group with spanish tags and english tags..
any idea?
Please let me know if you need the credentials to the web
Hoping to hear from you again.
regards,
Paco
