Answer 1

From my experience SharePoint is not very good to store huge amount of records (hundred thousands or even millions) in list. The reason is in the way data is stored in SharePoint database - if you check SharePoint content database you will find that all records from all lists on particular site collection are stored in one table AllListsData. The table itself is not really normalized so queries are not really fast and you get some performance loss because of the use of SharePoint as middle-ware. Moreover because all data from all lists are stored in one table if you have one huge list on site collection then it could degrade performance of whole site collection.
If you really need SharePoint I would suggest you to use separate sql database to store data and use BCS functionality to access it from SharePoint. Using this approach you can normalize data in your separate database and access data from SharePoint.

To get around it with the client Object Model you can use this code snippet, it uses item pos to leverage getting more than 5000K items. if you need VB.NET or more in-depth breakdown this is the site for you here The Snippet is from here
List list = ClientContext.Web.Lists.GetByTitle(“Assets”);
ListItemCollectionPosition itemPosition = null;
while (true) {
CamlQuery camlQuery = new CamlQuery();
camlQuery.ListItemCollectionPosition = itemPosition;
camlQuery.ViewXml = “<View>” + Constants.vbCr + Constants.vbLf + “<ViewFields>” + Constants.vbCr + Constants.vbLf + “<FieldRef Name=’Id’/><FieldRef Name=’Title’/><FieldRef Name=’Serial_No’/><FieldRef Name=’CRM_ID’/>” + Constants.vbCr + Constants.vbLf + “</ViewFields>” + Constants.vbCr + Constants.vbLf + “<RowLimit>2201</RowLimit>” + Constants.vbCr + Constants.vbLf + ” </View>”;
ListItemCollection listItems = list.GetItems(camlQuery);
clientcontext.Load(listItems);
clientcontext.ExecuteQuery();
itemPosition = listItems.ListItemCollectionPosition;
foreach (ListItem listItem in listItems) {
Console.WriteLine(“Item Title: {0} Item Key: {1} CRM ID: {2}”, listItem(“Title”), listItem(“Serial_x0020_No_x002e_”), listItem(“CRM_ID”));
}
if (itemPosition == null) {
break; // TODO: might not be correct. Was : Exit While
}
Console.WriteLine(itemPosition.PagingInfo);
Console.WriteLine();
}
