Hi and welcome!
First of all, it's a good thing that you have a clear plan on what you want. Stick to it, addiction will set in soon afterwards.
To start, read the stickies in the New members area, all the info and rules to help you make your experience here much better. There's obviously also the community, many members happy to help.
To start researching, you can use Google, by adding "...site:forum.replica-watch.info" to your query (e.g. VSF batman) you'll get a ton of threads from rwi. (at least for the batman I'd check also the clean factory offering, I think it's a good one either).
What you will not use Google for (never) is looking for TDs, use only RWI'S links in the dedicated section, scam risk in the net is high.
Any td can source you a watch, especially high demand pieces like the ones you mention. So, take your pick. Start by asking for availability, you'll establish a direct contact and have a first feel for the td, if you like it, go on with him.
As for the durability, we talk mainly movement here. It can be a hit and miss game here, some movements are not the highest quality and are sometimes assembled in suboptimal conditions (dirt), but most of the times it's OK, worst case you'll have to service at some point or swap movement if it dies entirely. But also here, I'm not 100% sure, but those high demand models you're looking for should be equipped with fairly decent movements. In the tech section there's a specific subsection on movements you can check out to learn some basics.
What else? Well, have fun, and if there's anything, just shout out.
