Answer 1

If you are trying to make production grade I would recommend URDL or Boost.Asio in general.

But if you are tinkering around for fun then consider Byte Ranges and multi-threading for async processing. Still asio would be the best bet for that too.

Answer 2

Qt classes - QNetworkAccessManager, QNetworkRequest and QNetworkReply classes will help you in writing your download manager.

QNetworkAcessManager::get() is used for download
