I always record dry, then add reverb to the guitar tracks and the vocal track separately - guitar usually needs very little (if any at all) and vocals a touch more. Remember that, in Reverb-World, less is often more - quality not quantity is the rule.

Olddude - sounds to me like you have some back-echo coming off hard surfaces (windows, walls, doors??). Also, try recording the guitar first, then add the vocal track, which will prevent bleed occurring between the tracks, then add your effects, do the mix and make a master. Works for me, and you're able to give your full attention to both elements - the guitar piece, and the vocal - should give a good result.
