Total Vote: 120,662,065 430 Districts
Democratic: 65,203,062 54.0% (52.9%) 417 candidates
Republican: 52,290,917 43.3% (44.9%) 395 candidates
Other: 3,168,116
The 2006 percentages are in the brackets.
This total covers 430 Districts. There were 5 incumbents (1 in Arkansas, 2 in Florida and 2 in Louisiana) who faced no challengers and did not appear on the ballot, they were reelected by acclamation. 4 of them are Democrats and 1 is a Republican.
Overall the Democrats ran 421 candidates and the Republicans ran 396 candidates.
I also compiled the Presidential vote and wound up with the same numbers as the official totals as presented on Dave Leip's website except for the 'other vote' where I seemed to miss about 150,000 votes. I'm not sure where the difference could come from except that I couldn't find the write in vote for every state. The relevance of that for this is that it wouldn't surprise me if the 'other' Congressional vote was a bit higher than the figure I have here, but not significantly.
2006 percentages are in partenthases. hesitated to put the 2006 vote percentages in comparison here, because the number of candidates than run for each party effects the results, and the comparisons can only be understood in that context, this is especially true in the cases where the Democratic share of the vote declined. So, if you're interested in why the vote percentages changed so much in a state, please check the 2006 results first. Of course, in many states, the Republican percent of vote just declined.

Note 2: In the cases of the 2nd district and the 4th district, a closed party primary was held on election day instead of the general election (the primary was delayed in those districts due to hurricans). The runoff was held on December 6. I used the runoffs numbers for the totals.
