When repointing, hold the fairly dry mortar in your hand and then use the pointing trowel to push it in. If I hold it on a regular trowel I feel like I get the mortar all over the place.
Its not that hard to do, just takes patience.
Grind out the old mortar and clean the recess well, Compressed air or a paint brush works.
I like to use an adhesion additive in the new mortar. I found it also helps to pre-wet the recess. This keeps the old mortar from sucking all the moisture out of the new mortar, providing for a better cure.
Masonry bags seem like a good idea but I haven't found that they work well. The placement process that EatenbyLimestone describes worked best for me.
