First off, Intel Yuck...
(Sorry im an AMD Fanboy)
Your going to need to buy a CPU fan that works with that processor if you dont have one already. Dont forget the other common stuff like cd-drives, a monitor, or a keyboard and mouse but im assuming you have or are getting those.
With ram the speeds of the sticks must match. If not they will find a common speed the, PC 3200 will slow down to PC 2100 speeds to match that other stick if you decide to go that way. If I were you I would buy two sticks of PC 3200 instead of a 1gig stick this way you can run your ram at pc3200 speeds and the ram would run Dual-Channel provided that motherboard supports it and most do nowadays but check this on the motherboards manufacturers page. You cannot run two different sticks dual channel they have to be identical, running ram dual channel offers a great boost in performance and with that mobo and cpu it would be a very wise addition.
Most motherboards come with a cd with drivers, one IDE cable, One Floppy cable, and a plate for the back of your case, and not always with a manual but usually.
And yes the processor and motherboard should work together or it wouldnt be much of a bundle would it.
Also make sure your powersupply has enough watts, and remeber when working on your new pc to take your time and think things through if you get frustrated like I always do take a break and relax.
