Normaly the higher the resolution the better _but_ many
cheap scanner just claim a high resolution but are crap.
Anyway, you will nearly never scan something at a resolution
higher than 300 or 400dpi as you won't have the memory :=)
For example, we consider that an image on a screen as
a resolution of 75 to 100 dpi.
If you make scan for printing, most laser have a resolution
of 300 to 600dpi. Most inkjet also except for the new
Epson who can go up to 1440 dpi ! But that doesn't mean
that you need to scan the picture at this resolution.

Usualy when I scan an A4 picture, I use 200 dpi. The
resulting image is already around 12MB ! And the quality
is much enough to enlarge the picture up to A3 or A2
when printing...

In fact a higher resolution is important for the printer
and much less for the scaner.
