I have no advice to offer in return and have been plaguing this board, but don't have an LFS and the books I have bought are so general that it raises a ton of questions.
Never Ever let that concern you !!!!!!!!!!!!! Sorry to sound harsh, but these boards are here primarily for new folks to learn. We all had our day (And still do) when we need to knowledge and experience of others. I would rather answer questions all day than have folks struggle and get less than they should from this hobby. Those who can answer questions, those who don't want to or don't know ask questions and follow along. we all learn something.
Now back to your issue at hand. I would agree With TKOS on the big plants. Unlike fish Plants can be stunted and managed in most cases without any concern of long term health issues. You may decide to change later, but now would not necessarily be the best time to do that. I Would bet on Green water as it is common in new tanks without good colonies of micro fauna. I would also not be overly concerned about it right at the moment. your primary issue is the cycle and your fish. test info will be very helpful but until you get your test kit, water changes are an absolute must. I personally would reccomend once daily water changes 40%-60% until you have the ability to monitor numbers.
The reason I would not worry about Plants or algea at this point is simply because both plants and algea consume ammonia, and ammonia is your biggest enemy in a fishy cycle. You could make the situation worse for your fish by trying to fight with plant issues and or algea issue right now.
So My personal reccomendation is to identify the coudiness (So you can prepare for later battles) Do frequent water changes, Get you test kits and get some numbers. I would also say that getting some Excell is a great idea as it will improve your plant growth and help with all situations at hand.
No matter how unsightly green water may be it doesn't harm your fish, So grin and bear it. once you know your cylce is complete (Via test numbers) then you can easily kill green water with a 3-4 day blackout. Once that is accomplished, then you can adjust lights, ferts, ect. to prevent the return of the algea blooms.
