Hi
I am new to Arduino have just found out it may do what i need it to do.
I need Arduino to control two servos independently ie with the remote up/down for one of the servo and left/right for other servo.
Speed would need to be controled as the servos would need to turn slow.
What componets do i need and how do i do it?
Thanks for your time and help
A quick google search returns a ton of information.
These may help:

Start with one servo, and once you understand how that works, then move to add the other one.
Have a look at the examples that come with the Arduino IDE - especially the servo-sweep example.
What are you thinking of using to provide the control inputs? - for example push-button switches or potentiometers, or a joystick that contains potentiometers.
Read as many Forum Threads as you can - they are a great source of knowledge, including "what not to do".
Have a look at planning and implementing a program.
This Thread about controls for an excavator may be of interest.

Below is a discussion on controlling the movement speed of a servo. Bottom is code for sending independent position commands to servos.

I would like control it via a 21 inch touch screen monitor connected to my pc. Would i need additional hardware to use a touch screen ?
Im buying one of theses are they good?

Did you read the reviews?
Yes i did see the reviews and it had loads of good reviews.
I bought one of the below and it worked as expected. $4.08 including shipping is a deal.
