DnD 3.5 Build – ‘Gravity Monkey’ idea with monk and druid

I’m about to start a DnD 3.5 campaign with a malleable DM. We are starting at level 5-8 (TBD) with 100,00 gold. I’ve been working on a build that has flavors of Sun Wukong – The Monkey King – at early levels and Pain from Naruto (almighty push stuff) at late levels. My goal is a ‘gravity monkey’ with a mantra of “The strength in this world lies in the sky and the earth.. and the forces that hold it together.”

I have approved the Wukong homebrew race and I will start with 2 levels of Monk as an orphan brought to a monastery in cold mountains (unless something more fitting is suggested). For the next several levels, I am planning to hit druid for the quarterstaff buffs and ability to summon elementals (Rashini Elemental Summoning as my idea). My end game is 6, 9, or 10 levels of the homebrew class, Mage of the Unseen Force (Gravity-mancer). I essentially want to be a monkey who hits hard and often, has battlefield control through earth and air spells, and can anytime fly around and summon elementals to supplement that control and then can start changing the gravity of the battlefield.

I’m looking for ideas for classes that might better fit the earth-air-monkey-quarterstaff thing if anyone has them.. BUT I am more specifically looking for alternative class features for the monk or especially druid. I know wild shape is great but I want to replace it to nerf my character a bit (my group isn’t heavy into optimization) and because I imagine myself pumping strength and staying in my form base most of the time. That said, the Monkey King has the power to turn himself into anything… I just don’t really want the stats from that – more the utility. I have looked at Shapeshifter ACF for druid, but it isn’t quite what I’m imagining as it seems to just buff stats if I’ve read it right. I can’t find much literature on the Elemental Druid ACF/Elemental Summoner Druid ACF, but it is very intriguing.

Question 1 synopsis: How can I make a druid (or something else) a nature-of-earth-and-air focused caster?

I also imagine myself as someone who doesn’t use many items. I want a badass quarterstaff (the Monkey King had one) that fits my ideas and have been trying to figure that out, but I am a bit unclear on staffs vs. quarterstaffs and whether a druid can use magic staffs.

Question 2 synopsis: Are there any awesome staffs that could be used as a quarterstaff and affect earth and air?.. or are there any other items that might be awesome for this build?

I will have some feats to spare. I will have my monk feats and am looking at quarterstaff focus, Rashini Elemental, and Magically Aloft for the homebrew prestige.. but otherwise have a lot of options.

Question 3: What feats work with earth, air, quarterstaff, or anything else that seems to fit?

Last notes: I live in China so anything with an Eastern flavor would be great. I don’t really want too much more homebrew as I have already added quite a bit, but suggestions are still welcome. I am not looking to be OP, just want a fun combat character. Our campaign is potentially going to be focused around finding a Deck of Many Things which my DM has a physical copy of. I don’t see that influencing my character really, but thought it was worth mentioning. I have read druid handbooks and Monkey King build threads, but am by no means well versed. I have looked at Apelord and Monkey Shen and neither fits right now, but if it makes sense with other options I am all eyes.

Thanks for the read and any answers in advance.
