Steadman's books look great; I didn't know about them (or they didn't exist) at the time I would have needed them myself, so I haven't used them. The only problem is that they they don't offer help with the first books of either the Iliad or the Odyssey, so you can't start from the beginning with them.
To me it looks like you are making good progress, so reading the whole Iliad and/or the Odyssey is a realistic goal. It will take time but it's worth it! If you want to do that (Do it! Do it!), my advise is to jump to the beginning of either epic as soon as possible and go for it.
If you decide you want read an entire epic, you'll probably need some help to that. I haven't used this one myself, but it's probably good (for Odyssey books 1 & 2), I have found other writings by Jones helpful myself:http://www.amazon.com/s/ref=nb_sb_noss? ... ssey+jones
Then there are all those other commentaries we have discussed earlier.
It depends of course on your budget; if you have access to a university library, you'll find most of these books there. If you're tight on budget and without a library, you'll have to rely on what you have on the internet, which isn't actually that bad either - Steadman and the (school) edition of Merry are probably the best now, if you don't know German.
