Scriabin's Etude in C# minor, op. 2 no. 1

[mosis]

I have started learning this piece, and I'm making quite some progress. I have half of it memorized already, and it is sounding good...

... hands and voices sepereately, that is. 

I cannot bring out the RH melody and keep the chords even. The chords are either loud, arpeggiated, or the melody is bashed out, or not heard at all. I am struggling with this, and although I'm sure this is what the etude is teaching, I do not know how to go about learning it.

I also find the fact that there are no slurs on the score to be peculiar. Listening to a recording, one can figure out the logical phrases and musical lines, but nothing was notated. What did Scriabin intend with his whacky time signature and utter lack of phrasing and articulation?

Ideally each hand should be able to play there part in many different volumes and styles atop the other.  The perfection everyone aims at.  However, the best way to progress here is to practive right and left seperately (as you have), and to isolate every aspect of the piece and work on it. 
Work through each hand with rythms and slowly.  Once you know it very well, you will be able to achieve good balance. 
Long-short and short-long are so effective at so much.  (this is a rythm alteration made to even-note passages)
Long-short:  Double the first note and half the second for the whole phrase (Swing feel)
Short-long:  Halve the first and double the second
eg.  a phrase all in quavers.
Long-short:  Dotted quaver, demisemi.
and so on. 
Play through once with each alteration then through slowly and improvements can already be felt.
