Answer 1

In windows phone 8, There is no control like FileUpload instead of that you need to use Background Agent to upload files. here are two Good Samples you can go through How to Upload a File from a Windows Phone App and Auto-upload Sample

Answer 2

If you are going to Upload Image files, then you can use the PhotoChooserTask to select file and upload file using the HttpClient Library.

For other file types, You can access ONLY if it is stored in SD card. See here for accessing files from SD Card in windows phone.

Only in Windows Phone 8.1, you can access the Downloads Folder.
