Hello Krames11 . . . Actually, you have a perfectly fine set of chords in your toolbox. Simply use Chordie's index to find songs by performers you like and then use the transposing tool to move the chords into your comfort zone(which seems to be key of G mostly).
You need to find songs that are formatted in such a way as to be transposable. Some selections are not in the proper form so they can't be manipulated. Generally, the songs that appear with blue chords above the lyric are transposable.
You will probably have to play with the transposer a bit before finding the chord set that you want. The chords used in each song (along with fingering charts) are listed in the upper righthand corner of the screen.
To broaden your palette a bit, you may want to learn G7, D7, A7 and Bm.
Hope this helps - happy jamming.
