Mainlymusicman, how do you like the tylers? I was thinking of getting the seas odin kit, which is very similar.
About the fiberglass panels, you have to experiment on their placement. I would treat the 1st reflection point first and listen for the improvement. Then 2nd reflection point and listen and so on. Sometimes too many panels will sound worse than no panels at all. I like my front wall to be fairly dead with some diffusion and rear wall live, but you may have different preference.
