Usually, you do not have to upgrade anything else.
If you are moving your current processor into the upgraded motherboard, your current cooling fan does not need to be upgraded.
To add a second processor to a computer, you need a dual-processor motherboard.
Yes it matters. if you want to use a computer for graphics then you need a fairly large processor. if you want to do games you need a big processor. if you want to upgrade your OS someday then you need to have a good processor. Also, the size of your processor effects your speed.
Because some processors are slow and cannot handle games and a certain amount of work.

Neither. Get a new computer.
To upgrade from Mac OS X 10.4 (Tiger) to !0.5 (Leopard) you will need to purchase a copy of Mac OS X 10.5 (Leopard) which costs around $190. However if you have a recent Mac with an Intel processor you can upgrade from 10.4 directly to 10.6 (Snow Leopard) at the $29 upgrade price.
To upgrade beyond Mac OS X 10.4 (Tiger) you will need to purchase Mac OS X 10.5 (Leopard). If the iMac has an Intel processor you can jump straight to Mac OS X 10.6 (Snow Leopard) but if it has the older G4 or G5 processor then 10.5 will be as far as it can go.
No need a upgrade. Just go to a local computer store and ask for a custom computer you can make and set a price and they will do the shopping for you. (: thats what i do! Just make sure you know what case you want. (:
