Serebii.net is usually a good place to start but for an actual walkthrough just Google Pokemon diamond and pearl walkthrough and you will get multiple results
In Pokemon Diamond, a very good place to go is North of the Fight Area. All of the many trainers have level 45-60 Pokemon.
all trainers i know u all have alot to accomplished good luck
www.psypoke.com and it tells you everything where it get Pokemon about shiny Pokemon everything check out more then just the walkthrough
I've added a link that you can find a walkthrough from.
Try searching ("Pokemon Diamond" + Walkthrough + Guide) on Google, or go to a game guide website. Here's a good long guide which lists practically everything to do with the game; http://www.gamefaqs.com/portable/ds/file/925601/45138
To get Burmy with the trash cloak form on Pokemon Diamond it needs to have previously battled in a building. Gyms and the Elite Four is a good place to change a Burmy's cloak to trash due to them having a large number of trainers in them.
A very good walkthrough for Pokemon diamond is the website Psypoke.It also shows many tips and lists of berries and where to get them,Tm's and HM's, and all sorts of stuff for Pokemon diamond and pearl.It also shows the same things for emerald and all the Pokemon games so far, plus they are making a guide for the new Pokemon platinum.It also has the best pokedex on the internet(in my opinion) and shows locations on click on maps where you can click on the route and figure out what Pokemon are there and how to get them(pokeradar,only in diamond/pearl, etc.)The website address is posted below as a related link.
once you have defeated all eight trainers and are on your way to the indigo plateau you will hit a cave, this cave is named victory road,(or so i believe) while in that cave you will come across a frog looking Pokemon in a spot, there are numerous guides i am sure to find the Pokemon once in there, one of my favourite guide/walkthroughs from Pokemon red/blue are "kodys kick ass Pokemon red/blue walkthrough" this is a good walkthrough, so go you youtube, look up "Kodys kick ass Pokemon red/blue walkthrough finding moltres" its a good guide and i trust it, hope this was helpful!
Scott is a scout that watches good trainers.
Well, If you want a walkthrough site try typing in: (verison ie. heartgold) walkthrough Pokemon Marriland, I've used it and it is really useful. Another site that isn't exactly a walkthrough site but still very very useful is seribii.net. Google: (version) seribii.net
Well, Chimchar is good fro starters in Pokemon, so it would be the best. Next, Turtwig is the medium for okay Pokemon trainers. Piplup is for challenged Pokemon trainers who are well experienced.
