I too am new to online poker (been playing for almost 2 months now). I, like you played exactly the same for the first few weeks, although I loved it I had no real progression, I was ethier up (mainly due to luck) or down (probably due to bad plays as opposed to luck)
I read everything I could on tips, guides and strategy and it just seemed to confuse me even more, a plethora of information does no good if you don't know how to use it and I found that I was concentrating more on what I "should" be doing rather than what I felt....and then I found a little program called Holdem Magic.
To be honest I have seen very little reviews of it or info anywhere but it turned everything around for me, it keeps the HUD down to a couple of essential bits of info so you don't get too bogged down and distracted too much from what is going on. It gives you information on your opponents playstyle such as calling station, rock, shark, fish etc. etc. and why, and best of all there is a helpful little box at the side of your table.
The box gives you info about your handstrength in the position you are in, gives you hints about how you should play it, what cards you need to flop and the % that they will.
Then after your session it tells
you how you played and what you need to improve and how to do it.
Now i'm not saying if you install this and follow it's guidelines and hints to the letter you will begin winning but it taught me things like positional awareness, stealing blinds, what signs to look out for etc. - it comes on a free trial and by the end of the 30 days I didn't really need it anymore as it had taught me the base of what I needed to know and now I just use poker tracker.
I play on 888
and I find that nearly every table there is a good mix of people and this software really does highlight the bad and the good quickly (although you'll soon learn how to work that one out quickly enough)
Although I'm by no means a good poker player and I still often make daft mistakes I still managed to get from my initial $10 deposit to just over $100 in about 7 weeks playing NL2 which I hope isn't too shabby
