Once you have the national dex at the start of the game in the Menu there will be an option that say "transfer pokemon from "(POKEMON GBA GAME)" in there you will be able to choose the pokemon you want to send over.
Once you have done that use surf and surf down from Sandgem town.
There will be a path of rocks which leads to the right. PalPark will be in that area.
At Palpark you will be able to catch those pokemon you transferred.
Hope this is helpful, I havent used Palpark for a while so I hope the details are correct

No, You can only play mulitplayer against games of the same generation. So as Ruby is a GBA game, you can not play against the DS releases (Pearl, Sapphire and Diamond). ALthough, if you own a ds or ds lite you can use the gba slot in import the Pokemon from your gba Pokemon games into the ds games.
