Single term limits might not be a great idea, since new representatives will have to rely even more on people who've been around Washington a lot (i.e. lobbyists) to write legislation (since part of joining Congress is getting ramped up on a lot of tradition/things you have to learn on the job).

Public funding of elections would help - take the current $2 they ask you about on taxes, and make that $100 or so. Then give proportional time to candidates with publicly funded money.

The other counterintuitive one is to bring back the secret ballot in Congress. Publicizing voting records actually makes lobbying more effective since the lobbyists can measure effectiveness of their $$. If you brought back the secret ballot, people are more free to vote their conscience without having to take the brunt of the blame for it (lobbying really took off after the elimination of secret ballots in the early 70s)
