TheSo, to properly hook up the generator, do I connect the frame of the generator to the grounding rod for the house (don't yet know how the house is grounded) or do I connect the ground of the 30 amp receptacle of the generator to the frame? Also, connect the neutral to the grounded frame? Kinda makes the generator not so portable.
Can't shop for the breaker set-up until I have a panel.
The device pictured above is not for the type generator you have. The generator you have should never be connected to your house unless you are going through a three wire transfer switch. Here is the User Guide Infomation that is in the UL Whitebook

Engine Generators for Portable Use
GENERAL
This category covers internal-combustion-engine-driven generators rated 15 kW or less, 250 V or less,
which are provided only with receptacle outlets for the ac output circuits. The generators may incorporate alternating- or direct-current generator sections for supplying energy to battery-charging circuits.
When a portable generator is used to supply a building or structure wiring system:
1. The generator is considered a separately derived system in accordance with ANSI/NFPA 70, "National Electrical Code" (NEC).
2.
The generator is intended to be connected through permanently installed Listed transfer equipment that switches all conductors other than the equipment grounding conductor.
3. The frame of a Listed generator is connected to the equipment-grounding conductor and the grounded (neutral) conductor of the generator. When properly connected to a premises or structure wiring system, the portable generator will be connected to the premises or structure grounding electrode for its ground reference.
4. Portable generators used other than to power building or structure wiring systems are intended to be connected to ground if required by the NEC.
Now the question is, are you wanting to do it right or are you just trying to make something work?
If it is the latter then a couple of #12 drop cords is the cheapest way out and still be safe. If safety is not a issue then do it how ever you wish.
At any rate the generator is a listed ungrounded device and driving a ground rod at the generator is not needed no matter how you wire it to your house.
