Driveline Service And Power Steering Fluid Flush

[youbetcha!]

I bring my 2003 Lx to the Toyota Dealership for oil changes and big things like timing belt etc... They recommended I do the Driveline Service $209.95 and Power steering fluid flush $119.95. Are these necessary? If probably a good idea to do them, do I need to have them done at the dealership or can any "mom and pop" mechanic shop do these for me?

For example, I would not get my timing belt done at a mom and pop dealership... To much involved and I feel more comfortable with someone who has done a timing belt on a car like mine.

Thanks for your inputs!
