Answer 1

in my opinion you never allow 4gb to upload at once, use segments. i suggest you to read following links, which has awesome explanation.

1. Large File Uploads in Asp.net - Jon Galloway
2. Dark side of File Uploads.

Suggestion :

1. Try some flash/silverlight based uploads (Telerik has support of silverlight upload) or SwfUpload
2. try to re-think about the architecture, how you are going to save 4gb+ data for each user? .

you can set maxRequestLenght attribute, but setting this value to higher, will lead to hacker to crazy things. and your server will get load.

Answer 2

The maximum size you can set in ASP.NET is 2097151Kb = 2Gb. If you need to upload files larger than 2Gb you must implement resumable upload interfaces and upload files with segments.
