Questions about running a SR2050-campaign Options

[nielsk]

I hope I find here some good suggestions for a problem I am having.
Soon I want to start a campaign based on Shadowrun 2050 (so SR4A-rules in the 2050-setting with some rule modifications like returned Grounding). And now I have some problems:

1) Shadowrun 2050 is not very helpful in regards of the character generation. The prices in SR2050 are (sometimes far) higher than those of SR4. Still you only get 5.000 Nuyen/BP. Does anyone has experiences in regards how to change that? I am worrying that when I am setting the money/BP too high Sams and similar concepts get far too strong while leaving it at the 5000 Nuyen/BP-level they aren't strong enough. Or is it not a problem at all and the mony-limit is ok that way? It seems to be only a real problem with Cyber- and Bioware while Fake SINs for example are still pretty cheap compared to 2nd Edition-levels.

2) Does anyone know a good source where is listed when which piece of equipment got introduced (incl. stuff like Beta- or Deltagrade Cyberware)? The equipment-list in SR2050 is pretty short and I am already wondering about Bioware. I thought that was earliest introduced in 2052. I would like to know what the characters could get and what is really cutting edge-technology or not yet available. The same for upcomings of magic etc. - when did which sub-meta race occured and stuff (changelings didn't happen before 2063 with the YotC, right? Drakes and AIs were pretty late, too afaik).

3) Regarding (2): I am planning to not allow taking Bioware during character generation because it is so new. Yay or Nay? I have a house rule-SOTA-positive quality which they could take if they still would like to use Bioware but what would be a good availability-adjustment

4) Does anyone know if there are conversions of the old adventures to SR4-rules are available (at least something home-made that only shows adjusted ratings)?
