If the wheels are not true, take them off, and get a shop to true them.
If they do not spin smoothly either, you could get the shop to service the bearings at the same time, or you could buy some cone spanners and do it yourself.
Buy some new tyres. GP4000s or GP5k. Buy some new brake pads. Any new road kind will work.
Grip the fork in one hand and the stem in the other, feel for play in the headset bearing. If it's rough, or there's play, you need a headset spanner, and a big adjustable, some solvent to clean the bearings, and some grease to repack them. It's not a very hard job. Definately do that yourself. You can cut most of the front reflector off with a hacksaw while you do that, and just keep the spacer bit. Clean and grease the stem too.
Take the seatpost out, clean it, grease it. Take the seatpost binder bolt out, clean the threads, grease them lightly.
Drop your chain off the crank to the inside, spin the crank, is it rough? If it's REALLY rough, definately replace it (or try service it first, but a cartridge replacement is cheap) if it's a bit rough, you could ignore if it's not loud to ride.
Get some new platform flats or clipless pedals
Get a chain tool, and a new chain and a new cassette/freewheel if the teeth are worn (compare to each other)
Buy a bicycle specific cable cutting tool and recable what you want. Rewrap new bartape. Pink to match the decals would look best.
Any bolt you remove, clean the thread, and lightly grease it.
Tune it.
