cas (may i call you cas? lol) join livemocha, at the end of each lesson there's a review and then a written and spoken test, which fluent/native speakers review for you. so if you have a mic you can record stuff and someone will give you tips on pronunciation etc. i don't have a mic so i've been skipping that part but one of these days i'll hijack my husband's computer and go back and submit them all lol.
i haven't explored too too much but you can add friends, i wonder if you can voicechat with them. the site even suggests friends for you who are studying at the same level.
or become friends with someone Japanese and talk to them on skype or something :p
myself i'm focusing more on understand and reading right now, speaking it will come along naturally. i get how the pronunciation works anyway, the hard part for me i think will be words that don't have direct translation (like the way to say clever is actually something like 'sharp in the head')
but yeah i try to do one lesson per day, either livemocha or rosetta or right now the irasshai videos mostly, and then before i log off for the night i practice reading hiragana
