I would agree that an emp is a good starter scorpion and a rose hair is a good starter T. A rose hair was my first tarantula. You just need to be careful getting your first rose hair because I have seen A LOT of psycho rosies. Just make sure you pick up a nice calm and docile one and I bet you will not regret it If a rosie is not your thing a few others come to mind (but some are slow growers and/or hair kickers):
Grammostola pulchripes (get big if you want a bigger T)
Grammostola pulchra
Brachypelma smithi
Brachypelma emilia
Brachypelma albopilosum
Avicularia avicularia (if you want an aboreal)
