The 28th Amendment is...

Well there is a proposed 28th amendment to make all laws applicable equally to all citizens as well as Congress.

Limiting the amount of money/time that candidates can spend on Federal general elections

I would suggest some ideas that should be considered. I base these ideas on the fact that Congress is the problem with our government, its growing increasingly stagnant, year after year.

1. Term limits for U.S. Senators and Congressmen. This is not a new idea. Many states and cities already have these rules in effect for their mayors, govenors, and state house/senate representatives. I propose two 6 year terms for Senators and four terms for House members. Which translates to a maximum of 28 years (see next point) a person can serve in Congress.
2. Instead of 2 year terms for House members change them to 4 year terms. The reason for that change is because every other year is an election year and the pace of Congress gets slower and slower. Instead of House members trying to score political points every other year, make their terms longer.
3. Get rid of the August recess for Congress and the President. The origins of the August recess date back to Colonial times when D.C. was burdened with unbearable heat. We have A/C now and Congress is slow enough as it is without taking a whole month off.
4. Set minimum amount of years (say 15-20, for example) for how long a politician must work in Congress before getting pension pay for life. Some politicians serve for 2 or 6 years in Congress and never run again, but they still collect a gov't pension for time served, for life. That's a whole lot of tax dollars being pissed away.
5. Revoke Congress's right to vote for pay raises for themselves. The excuse is that Congress is also voting for pay raises for general gov't employees such as various agencies, USPS, etc. I don't see a problem raising gov't employee salaries with the rate of inflation, but Congress's salary should be entirely separate and contingent on the votes of the people in their state/district.
6. Revoke Congressional Heathcare till they fix the problems that plague our healthcare.
7. Gradually privatize USPS, it's an old, largely un-needed gov't entity. Make exceptions for the poor, for example.
8. Give people the option to opt out of Social Security. Once they leave, they're on their own and would have to pay a hefty fine if they want back in.

Proportional representation in the senate. The relationship between the states and the federal government has changed a great deal since the senate was created. It no longer makes senate that Wyoming and Alaska have as much say in what goes on as states with 20 times the population. Actually, I'd like to see the senate abolished and congress replaced with a unicameral parliamentary body.
