''On distant islands in the South Atlantic young men are fighting for Britain.

Like two families planning a wedding, the New York City Police and the sponsors of Saturday's disarmament demonstration have been meeting day after day to check -and sometimes tactfully negotiate - the final arrangements. The police, who expect up to half a million people to converge on the city for the rally, said the planning had taken a month of meetings. During these sessions, the two sides have negotiated everything from the police plan to have mounted officers patrol the rally to the organizers' request that they issue their own parking permits and that two of the city's trees be cut down. Although the police denied some requests, they did agree to set aside 100,000 of the best spots at the rally for actual demonstrators, as opposed to music fans out for a day's entertainment.

Argentine warplanes bombed and damaged the British frigate Plymouth and two landing ships tonight, causing at least five casualties, the Defense Ministry announced. In the first intensive combat between British ships and enemy jets in the Falkland Islands war in 10 days, two Argentine aircraft were shot down, the ministry said in a statement issued just before midnight. At least five planes were reported damaged, with one possibly destroyed. In Buenos Aires, the Argentine command said tonight that its planes had attacked British forces making an amphibious landing at Pleasant Bay, 16 miles southwest of Stanley, the islands' capital, sinking a frigate and damaging three landing craft.

Once again, the General Electric Company is going it alone in lobbying Congress on taxes. It opposes the Administration and most of big business on tax leasing. It opposes the Administration's proposal to strengthen the corporate minimum tax, although it has not joined a coalition of 20 companies also opposed. In a move that set tongues wagging in Washington tax circles, G.E. recently retained a high-powered lobbyist and political fund-raiser, J.D. Williams. In all, as Congress searches for ways to raise revenue and shrink future budget deficits, G.E. is living up to its reputation as a special presence in the tax-lobbying arena. ''A lot of companies come and go in the tax fight but G.E. is one that stands out all the time,'' says one of Washington's best-known tax lobbyists, who asked not to be identified.

Israeli tank columns and infantry units pushed as far as 32 miles into Lebanon today, driving toward Beirut from two directions in an apparent attempt to trap as many Palestinian guerrillas as possible. One advance column was said to have reached the village of Baruk, 15 miles southeast of Beirut. The Beirut radio said the column was exchanging fire tonight with troops of the Syrian peacekeeping force who were on the Beirut-Damascus highway about eight miles to the north. A Syrian military spokesman said Syrian tanks, helicopter gunships and artillery clashed with the Israelis at several points in central Lebanon. But thus far the Syrians appear to have refrained from throwing the full weight of their armed forces into battling the Israelis.
