Thing that are not that hard to do and will be quite usefull for your army.
General advise :
Give your warbozz a lucky stick. Model it on him somehow, and you have the most used
HQ in the ork army book.
Get more claws add claws to the nobz. ( you want 1 claw nob on 11 boyz for trukk boyz build and a green tide army also needs way more claws)
Get a few deffkopta's you don't have any and they are good don't leave home without them.
Build yourself some scratch build mek guns. you could be fielding 4 of them with the grots you have.
You have a lot of boyz ( like most old ork playes) the sad thing is ork boyz aren't really that good any more and most players have switched to other units but there are a few ways to still use them.
This will give you the option to at least run your army as a green tide. This is fun to field once in a while, but it is not really a flexible build and gets dull fast (both for your opponent as for you).
You could also field your army in a more traditional way. Multiple Blobz of 30 slugga boyz with 1 power klaw nob in each unit backed up with some loota's and other shooting stuff. This might be more fun to play but isn't really that viable vs most modern lists.
Trukk boyz requires you to have trukks. you will need 1 trukk per (11 boyz +1 nob) so this will be a lot of trukks. This build kinda works and is one of the few lists currently using a lot of boyz.

CAD + The Green Tide?
Warboss from Tide grabs Bigboss pole, Big Mek grabs Mega Force Field + Painboy. 100 Ork Boyz with 4+ Invul and 5+
FNP?
You can. This is the traditional way to field it. but it gets quite expensive if you also want to pack some oomph. And remember that 4++ is only for MODELS within 6" of the mek.
If you are going for this and actually like it then you might also want to invest in some aircrafts since ork planes really benefit from the all turn waaagh.
Automatically Appended Next Post: There is a modern alternative I forgot to mention. That is the ghazkull warband formation thingy + the core formation out of the new waaagh ghaz formation. It gives you waaaagh from turn 1, and a overprized ghazz deathstar. Not the best build in the world but it might just be an interesting alternative to play with and you almost have all the models for it.
