Firstly, what is your experience level with tarantulas?
Secondly, both "burrowing" Ts that you selected are mildly aggressive in my opinion and for your arboreals, The Lapropelma violaceopes(Singapore Blue) is also wuite aggresive and grows huge, The avicularia Versicolor(Antilles pinktoe) is reputed to be very hard to keep as then tend to drop dead for no appaprent reason at all.
So what I suggest in getting for the terrestrial is one of the sp. of Brachypelma, Grammostola or even a Cyriocosmus! (They are a dwarf specie but truly make some awesome webbed tunnels and are not aggressive at all - view the forums online shop

)
As for an awesome arboreal, Id recommend an Avicularia avicularia(Common pinktoe) firstly because its a lot cheaper that a versi and a lot hardier! Best started arboreal in my opinion

As also previously stated by Marius , the Tapinauchenius sp are also alot of fun

I have Tapinauchenius cupreus (Violet Tree Spider) avail. PM meif your keen :angel:
Otherwise, you can do what you want! My first arboreal was a P.regalis kungfu
Choose well!
