You say your new to linux so you may be asking for the method of how to do this with the wrong command.
There are several ways you can do what your trying to achieve.
Keeping things simple i'll have assumed you've 'cd' (change directory) into the path/folder where your going to be working. This is why my example don't include any '/' at the beginning of the folder name.
Copy contents of dir1 to /tmp/dir2
cp -a dir1/ /tmp/dir2/
Copy contents of 1 to 2 but this is more from a backup point of view but is a very useful command.
Moving the directory from one to the other(basically renaming)
This means that dir1 and all of its contents will now be called dir2
Hope this helps, otherwise try to be a little clearer into what you intend. Because using wget seems incorrect for what your are asking for.
EDIT:- I didn't notice you wanted to get it onto SVN as well.
Assuming you have SVN set-up with Apache/DAV support (as your talking about wget then i assume thats the case). Wget is the wrong tool for uploading to an SVN repo. If your talking about uploading after completing an SVN checkout? then you just need to use svn commit to upload your changes. If you used wget to download your files from SVN then things will be more complicated i think, your better off doing things properly and using svn checkout and svn commit, or using an SVN gui that makes things work similar to an FTP gui which for you might be a better place to start
