Which is the best Intel processor to go for?
well, the fastest/most powerful processor is the intel Core-2-Duo. but it carries a higher price tag so it may not be the "best" depending on your budget.

what is the difference is between a Pentium D and Pentium 4?
simply put, the Pentium-D is a dual core Pentium-4.

that depends on your personal computing needs and your budget. a dual-core CPU will excell at multi-threaded applications and multi-tasking, but will not offer any performance boost for single-threaded applications (as most still are even today). the 2 cores on a dual core CPU cannot work as 1 single core, so a single threaded application will only run on 1 of the 2 cores.
since a dual-core CPU costs more, then you may benefit more from a faster single core CPU for the same price. even though dual-cores have been out for a while now, they have only recently entered the mainstream computer market. so as we move into the future, more and more applications will be written to take advantage of multi-cored CPUs.
as far as choosing which one, I would suggest you set a budget, then see what is available in both single core and dual core models and decide whether you want 1 fast core, or 2 slower cores.
also, why are you only considering Intel CPUs? AMD Athlon64/Athlon64 X2 processors outperform Pentium-4/Pentium-D processors

is a big cache essential?
essential?, no... does it help?, yes.
- the larger the L2 cache = the faster the CPU can access the data it needs
- the faster the CPU can access the data it needs = the faster it executes it's command
- the faster it executes it's command = the higher overall performance the processor achieves
