Yes, that is a great suggestion, however, The bass Clef Real book(as are all 'the real book' series) are illegal and hard to find.
Your next best bet if you can't find a bass clef real book, would be to check out the bass clef version of 'the new real book' I think that currently volume 3 is the only one in bass clef, which is lame because volume 3 is more moving into blues and soul standards than jazz standards(not that I'm complaining, but I would like the bass clef real book) Fake books are expensive though!

I was at the Berklee bookstore today, and they are all like $40, pretty lame, but then I guess it's a small price to pay to learn some stuff.
the best suggestion is to transcribe though, that will do wonders for your understanding of music, your ability to read, and your ability to play a chart.
An exercise I used to do, that really helped my reading(which isn't that great admittedly, but it'd be a lot worse if I never did this exercise, and a lot better if I hadn't stopped)
take a piece of sheet music, and basically just fill in note heads, don't worry about stems, just do the heads, fill up the whole page in randomized note heads then just read through it verbatim, throw in some rests here and there once you start getting comfortable just reading notes, now, once you have exhausted that page, turn it over and read it that way. It may not be very musical, BUT, it will help get your reading 'chops' down somewhat.
but yeah, transcribe, transcribe, transcribe
