I need to know the default port settings for the following services
I neeed to know the port settings for these services for different versions of SQL Server (2000,2005,2008)
Also let me know whether the default port setting will change based on sql server versions
Thanks in advance.

If you have access to the server then you can use
select local_tcp_port from sys.dm_exec_connections where local_tcp_port is not null
For full details see port number of SQL Server
The default, unnamed instance always gets port 1433 for TCP. UDP port 1434 is used by the SQL Browser service to allow named instances to be located. In SQL Server 2000 the first instance to be started took this role.
Non-default instances get their own dynamically-allocated port, by default. If necessary, for example to configure a firewall, you can set them explicitly. If you don't want to enable or allow access to SQL Browser, you have to either include the instance's port number in the connection string, or set it up with the Alias tab in cliconfg
(SQL Server Client Network Utility) on each client machine.
For more information see SQL Server Browser Service on MSDN.
1433
the default port hasn't changed yet
SQL Server default port is 1434.
To allow remote access I had to release those ports on my firewall:
Protocol | Port
---------------------
UDP | 1050
TCP | 1050
TCP | 1433
UDP | 1434
We can take a look at three different ways you can identify the port used by an instance of SQL Server.
Using Windows Application Event Viewer
USE master
GO
xp_readerrorlog 0, 1, N'Server is listening on', 'any', NULL, NULL, N'asc'
GO
Identify Port used by SQL Server Database Engine Using SQL Server Configuration Manager
Click Start -> Programs -> Microsoft SQL Server 2008 -> Configuration Tools -> SQL Server Configuration Manager
In SQL Server Configuration Manager, expand SQL Server Network Configuration and then select Protocols for on the left panel. To identify the TCP/IP Port used by the SQL Server Instance, right click onTCP/IP and select Properties from the drop down as shown below.

You can use SQL Configuration Manager to set individual IP addresses to use dynamic ports or not (value of 0 = yes, use dynamic port), and to set the TCP port used for each IP.
But be careful: I recommend first mapping out your instances, IPs, and ports, and planning such that no instances or IPs step on each other before starting to make changes willy-nilly.
