haha! You sound like me. I get so indecisive! I'm willing to bet that your bulbs need replacing. That aside, the plants you have WILL do better with a bit more light. I know this, because mine would, too - even though they're growing well.
I'm still really no help with lighting. . .
BUT. . . you'll have a lot more options available to you with brighter light, and if it does turn out to be too much light, there are ways to fix it - some of which you mentioned above. You've had your tank a while, you know it pretty well, and you'll be watching. Algae doesn't take over everything in a heartbeat. Faster with brighter light, but I'm sure you'll see it, and make the needed changes, before it gets out of hand. It might throw you off for a little while, but you'll figure it out. We always do, eventually! And, in the future, you'll have a bit more wiggle room for different types of plants, if you choose to take that route. :)
Good luck with your decision!
