for doing it yourself, that's pretty neat. Usually for English, people use a method called "CV VC." That is, the word is split in half: [consonant + vowel] in the first part, then [vowel + consonant]. What I'd do is get used to using CV VC English banks before you go and record them, unless you think you're fine without doing that.
It's going to be very very very hard to record your UTAU without a reclist, I'd grab one and start recording from it. Chezziechan has some awesome tutorials on pronunciation, use, and configuration of English banks on YouTube, most people use her reclists as well. As for OTO.INI, that's pretty much a must for all UTAUs, regardless of language. For English it is tough in the beginning, but all the CV parts are OTOed identically, VCs are OTOed identically, so on and so on. So like a quarter of the way through you will be used to doing it.
Oh, and there are two reclists: one for lite and one for full. Lite has less recordings but is more limited, and the full has more. It's up to you to decide which you like best.
Also yay you're doing Daisy Bell. ^^
