Still the 5th string still buzzes when pressed on 2nd, 3rd and 4th frets.
Other strings are okay. May be time for new saddle and strings...
I would check that neck out well. Something is not right if you had to shim it up that much, and its still buzzing. As rparker said you need to set down and get some baseline stats done wiht it. Check the neck. Not only for bow, but for twist. I have the same guitar and the neck has a slight twist in it. So nomatter what I can never get the action perfect. It was free.... so it works till I can swing a new one... Once all aspects are sorted out.... then you know where the problem parts are.... and you can get a better idea what mods are needed.
As for strings.... Ya, if it still has the strings it came with.... OH YA you will need new ones!!! the OE ones are pretty bad!!! I did not read the link posted yet, but when you get into setting up the guitar, thats one thing you always do. Change the strings.
