What is max number of Query Arguments supported in the GET Request and in total how long can this GET request be?

Similarly for POST Requests.

Finally, Good resources for Base64Encoding and Multi-part Form Post requests would be great.

HTTP 1.1 specifies

The HTTP protocol does not place any a priori limit on the length of
a URI. Servers MUST be able to handle the URI of any resource they serve, and SHOULD be able to handle URIs of unbounded length if they provide GET-based forms that could generate such URIs. A server SHOULD return 414 (Request-URI Too Long) status if a URI is longer than the server can handle (see section 10.4.15).

  Note: Servers ought to be cautious about depending on URI
  lengths above 255 bytes, because some older client or proxy
  implementations might not properly support these lengths.

No restriction on Content-Length (for POST requests) is specified.

Internet Explorer is limited to 2083 characters in the URL: support.microsoft.com/kb/q208427/
All other browsers have a higher limit as far as I know, but you should keep safely below the smallest limit found.

The limit of a POST request is how large a request the server will allow, one common limitation (found in most Window servers) is 4 MB.
