The best way to determine sun exposure is to try your intended setup (lens,
filter, slide film) shooting a roll with a full range of exposures of the
plain sun -- no need to get Venus around, yet ;-) However, the day of the
Transit I encourage you to bracket, just in case...
If you need a starting point, last time I shot an eclipse I used 1/60 at
f/22, home-made filter and Kodak E200.

It's called NEAT (Comet C/2001 Q4). I took several shots (all without
tracking -- just a tripod) on the EOS300D, mostly with the Zuiko 85/2, plus
some with Zuiko 28/2 and Tamron 200/3.5. Here are a few samples; some are
1:1 crops from the original 3072x2048 file, and the rest are downsized
versions of the full pics. Unless otherwise indicated, the only PS
processing was a (constant) gamma correction (1.41)

Some pics of other sky objects, taken the same day... errr, I mean, night ;-)

Finally, a few pics of no scientific interest, just for fun (all Zuiko 28/2

The same here... but this time, chimping was most helpful: I had to shoot
several pics with the 85 around the expected area, until the comet showed
up on the LCD ;-)
Enjoy,
