You have a limited amount of RAM in your machine. Each process thinks it owns the entire machine, it has all the processor avalible, and it has infinite RAM. In order to do this, the OS has a swap system. When something is put into RAM, it is placed into a 'page' in RAM. When a page is not being used, then it is 'paged' out, and put into swap, which is on the hard drive.
As you can imagine, using swap is a great idea, but your hard drive is slow as compared to RAM, so if you have more RAM, you do not have to swap as much.
As for the number of page ins/outs, I dont see that as a problem. It just means that more stuff is being pulled out, than was being put in.
The question you want to ask is, over what time period did this occur? On my machine:
[bob@Freebird] ~%uptime
18:59 up 1 day, 5:36, 4 users, load averages: 0.18 0.14 0.14
86047 in
37538 out
This is normal to me.
