Congratulations on your pup's first bath! They are pretty funny looking when they are wet.
Grooming is a learning process. You will be a pro in no time. Mane and Tail -- good choice!
For taking care of the hair under the eyes, you can use a small comb. I like to use a flea comb with closely spaced teeth that gets all of the crusties and any other junk out:
Safari Flea Comb Also separates the individual hairs. You can find them at most pet stores.
