Which drivers are you talking about? If its the PC suite for connecting your mobile to the PC here's the link Samsung PC Suite.
If you are looking for some special software,so let me tell you that I myself have tried some but some worked and some didn't...don't trust the third party software.
I can give you a link from where you can download the games for your mobile,here it is Samsung Games
Similarly for the wallpapers I would recommend this software Samsung Wallpaper Creator
small in size but handy for creating wallpapers for your mobile where
you can have 3 wallpapers in one and slide according to your choice on
Click on the link and go to the download Tab on the top
and download the Zip file which is of 2.5 Mb aprox. Install on the PC
and start creating wallpapers.You should use 240 * 400 size wallpaper
aprox.each in the box.You can search for that size of wallpapers.
I will keep updating if I find any good softwares.
