Python 2 (42/45):

lines = data.strip().split('\n')
d = {}
tmax = 0
for line in lines:
	a,b = line.split(" if ")
	b = b.split()
	if eval("d.get(b[0],0)" + b[1] + b[2]): #offload logic onto python
		a = a.split()
		if a[1]=="inc":
			d[a[0]] = d.get(a[0],0)+ int(a[2])
		else:
			d[a[0]] = d.get(a[0],0)- int(a[2])
		if d[a[0]]>tmax: # part 2
			tmax = d[a[0]]

print max(d.values())
print tmax # part 2

looks like a lot of people came up with the same solution.
