You can upload files into your Sharepoint repository in one hit along with metadata (ie custom column information and values). You just have to Reference the SharepointSite/_vti_bin/copy.asmx (e.g. http://dev-moss/sites/home/PropertySharePoint/_vti_bin/copy.asmx) to get access to the Copy.CopyIntoItems() method. You then simply pass in the stream and Array of FileInfo objects (which have your metadata) into this method. I have seen several examples around that use the Http PUT method (e.g. http://www.sharepointblogs.com/ssa/archive/2006/11/30/wsuploadservice-web-service-for-uploading-documents-into-sharepoint.aspx)and and then grab the file back and update it with the meta data. My code sample below shows a much simpler way. I have not seen this technique is some of the larger Development guides such as SAMs MOSS 2007 Development Unleashed - they only give a passing mention to the copy service. MSDN also brushes over this service - http://msdn2.microsoft.com/en-us/copy.copy.copyintoitems.aspx
