Asking first is a very solid idea. Ill try to explain as best as I can. Here are several links to youtube videos that show the basic disassembly of the rifle so you can clean the dirt out.

In the first video it shows him taking the buttplate off. you shouldn't need to do that.
Important things to pay attention to:
1. Take your time!
2. When you are removing the bolt make sure the safety is in the upward 12 o'clock position. Otherwise you will have trouble disassembling and reassembling the bolt.
3. In the first video it shows him using his hand to depress the band spring in order to pull the front band off. Sometimes it takes more force to depress the spring than you can do with your hand. I recommend using a wood clamp with rubber jaws. So that you dont mar up the wood or metal.
4. When removing the action screws make sure you use a flat head screw driver that is the correct size for the screw you are trying to remove. If you use a screwdriver smaller than the screw you are trying to remove, you will probably mar up the screw slot. Which is not good.
As far as things you will need for cleaning:
1. A cleaning rod. It must be long enough and the right diameter for the bore of your rifle. Preferably the rod should rotate freely of the handle.
2. Cleaning patches. These are the patches that go into the slot of the cleaning rod, which you use to clean the bore. I typically just use cut up old t shirts for this. But you can buy patches that are specifically for this purpose.
3. Cleaning oils. There are many different types of oils that you can use to clean the bore. Most people have a preference. But just about any gun oil will do the trick. Old timers love "hoppes #9". Some guys prefer "Remington gun oil" and others prefer to use "ballistol". There are countless types and brands of gun oil. Motor oil is not the same thing. Its important that you dont go overboard with whatever gun oil you choose. A light coating on the metal will do it.
Here is a basic video on cleaning the bore, there are plenty of videos on the subject:

Hopefully you have a gunstore near you. If you do any gunstore worth its salt should have everything you need to clean your rifle.
