Unless the front seals are totaly different than most American cars and older Volvos The seal should be one piece. The metal holder you mention with the neopreen seal attached inside of it. When placing it on the inner hub of the wheel, it will be bigger than the hole by a very slight amount as this is how it is retained. You can place it over the hole and using a block of wood that is a little wider than the seal. Tap it so it enters the hole evenly. Usualy when you get it flush all the way around, you are in place. It is realy simple. Sometimes if you are trying to use a hammer to tap it into place you get it in on one side and it pops up on the other. Using a wood block applies even pressure all the way around and shouldent distort the seal as it is being tapped in. Grease the bearings (after cleaning them in some gasoline or solivent and then drying them)only by putting a gob of grease in your palm, drag the bearing through it forcing the grease into and around the rollers. Wipe the extra off the spindle and reassemble with the new seal in place. All that extra grease inside the hub does you no good and can overload the seal causing it to leak grease on the brakes. When tightening the nut on the spindle..... Take it down snug, back it off and then just take it down untill the play is gone. Remember that steel will expand when hot so a very snug bearing becomes a very tight bearing when it is hot. Use good high temp grease and you should be god for many, many miles.
