As you enter the town, use the Center and Mart as per usual. Outside of the Mart is a Black Belt who will hand you TM75 (Swords Dance).
Swords Dance is a move that boosts the user’s Attack by two stages, effectively raising it by 100% to doubled, then tripled and quadrupled! Of course, in many battles, you don’t have time to waste using this lest you get KO’ed, but it’s viable at times, particularly with setting up Pokémon.
(Setting up is when you bring out a Pokémon that has a huge advantage over the foe, which would logically force them to switch in fear of their Pokémon being KO’ed, and then using your "free" turn to boost your stats, rather than to attack blindly.)
In the Pokémon Center itself, a Pokémon Breeder will hand you Moomoo Milk for $500 per bottle; it’s a pretty good deal as it heals 100 HP! Much better than those Super Potions and Hyper Potions, and cheaper per-HP.
Also, you can go through the pink doorway in the northwest corner and use the Dowsing Machine in the hot springs to find an Ice Heal.

In the main village, an elderly woman on the west side will hand you a Pokémon Egg - if you have a slot in your party. This will hatch into a Pokémon after taking a rather large number of steps; it eventually hatches into a Lv. 1 Wynaut , if you need one.
In the southeastern corner of the town, you can find the Herbal Shop. The medicines there are more effective than normal medicine, but they also make your Pokémon less happy.
Happiness is important for evolving certain Pokemon or for optimising the damage for the Return move. That said, if none of that applies (and you don’t feel bad for torturing your virtual creatures), feel free to stock up on some. Well, it is the most effective treatment.
You can also speak with the man near the counter for a Charcoal , a hold item that boosts the power of the holder’s Fire moves by 20%.
If you’re ready for the Gym, get on in there! It’s in the southwest corner of town.
