i say 100%, learn how to write and pronounce hiragana and katakana from the get go, and never look back at romaji.
if you're practicing japanese on a somewhat regular basis, forcing yourself to always use kana will hammer it into your head and keep it there. if you rely on romaji, you will not learn it nearly as fast.
i also say learn how to pronounce it because japanese is a very simple language to speak well, IF you simply learn how to pronounce the kana well. having spent a little time learning and living in japan, i can definitely spot the がいじん who took the time to do this and those who did not. there is a clear difference. japanese is not a language that should require years of practice to pronounce well, like English. in my opinion, it should only take weeks.
one final incentive to learn kana... japanese is a very difficult language to read (they say you need to memorize 2,000 kanji to fluently read a newspaper), but a surprising number of words are borrowed words from english written in katakana. you will see these all over signs, advertisements, and menus in japan if you ever come. so while being able to read FLUENTLY may take years and years of study, you will be able to get around quite a bit just with katakana (also, if you learn how to speak english with a katakana-like accent, you will be much more understandable to typical japanese people when you need to use it!)
ok, that's my brain dump. hope it helps! がんばって!
(one last thing, if you're learning on your own, make sure you learn how to write your kana, and eventually kanji with the right stroke order (don't just look at the kana and try to copy them). it will make a significant difference in your legibility and ability to memorize, especially as you continue on with more difficult kanji. ok, that's it! good luck!)
