This article has a recommended reading list to get acquainted with mongoDB:

- Case Study on Switching to mongoDB - Very insightful and well-written article on why a company went from MySQL to MongoDB and the issues involved in their migration by David Mytton.

JavascriptMVC - a fabulous framework
http://javascriptmvc.com/
I did a sample project with this. Looks exciting, but there is definitely a learning curve.
There is a nice discussion of the merits of even attempting to do this in javascript here.

Stored Procedure to Count Rows in Dynamic SQL
The first parameter contains the dynamic SQL string. The second parameter is an optional column name the count statement operates on; the default is *.
/*
Counts the number of records in a dynamic sql string. Example usage:
declare @records int
exec @records = usp_CountRowsInDynamicSQL 'select recordId=5 union select recordId=6', 'recordId'
print @records
*/
Create proc usp_CountRowsInDynamicSQL (@sql varchar(800), @colNameToCount varchar(50) = '*' ) AS
declare @rowCount int
create table #tmpRowCount (row_Count int)
set nocount on
set @sql = 'insert into #tmpRowCount (row_Count) select count(' + @colNameToCount + ') from ( ' + @sql + ') x'
exec(@sql)
set @rowCount = (select top 1 row_count from #tmpRowCount)
set @rowCount = isnull(@rowCount,0)
set nocount off
drop table #tmpRowCount
return @rowCount
