i have that same Milwaukee drill/driver combo - it was a good deal at home depot. i don't have a lot right now. my dad has a lot of tools since he is in his late 60's
so if i don't have something i usually borrow it from him. when i bought a house i asked other homeowners IRL what was most important to get and they all said to get a cordless drill/driver.
i would say:
1) drill/driver with charger + set of bits
2) crowbar/prybar (they make hammer combos too which are sick)
3) hacksaw (need to buy one
)
4) utility knife
5) ratchet set
from everything i've read you can basically get everything you need for under $200. i still need to plant a lawn in a few weeks and then i'll be buying a pushmower since my yard is only 20'x30'.
my girl's dad gave me a sick ladder for christmas too. only used it twice so far but it's pretty great. it's a TITAN. don't know anything about it but it's one of the best ones i have ever used.
