I'm looking for a little advice on a certification path (or a career path) to help me push on from where I am.
Currently I work in a 'small' (100 employees) service / repair company in the internal IT team, I've been here for over 5 years. The company is not very supportive when it comes to improving my skills and offers very little hope of a decent pay rise, but does have the benefit of only being a 10 minute drive from where I live.
I seem to be solely in charge of looking after the network, servers, workstations, and phone system, along with providing internal support and regularly fixing problems on our internal database systems (there are four! we currently have a contractor in writing a new system to replace the lot, it can't come too soon).
Currently I work with:
Server 2003/2008/2008R2
Hyper-V Server 2008 R2
SQL Server 2005
Exchange Server 2003
ISA Server 2003/2006
Windows XP/7
Office 2003/2007/2010
Various third party software
I'm looking to challenge myself and increase my marketability, skills, and self-confidence (especially when it comes to getting a new job). I enjoy pretty much everything IT and love knowing how things work, but struggle with a lack of focus and lack of discipline with theoretical studies (I'm hoping the discipline will come with focus).
I want to go for a CCNA first, and started reading Todd Lammle's CCNA Study Guide last weekend (It's been nice to discover that I can still soak information in, I'm thinking about what I've read often and feel keen to continue

). Following that, I'm not sure (the sensible start would be CCNA>MCITP-SA>MCITP-EA, I think).
The following have me interested and would directly relate to my current job -
MCITP-SA (70-640, 70-642, 70-646)
MCITP-EA (MCITP-SA, 70-643, 70-680, 70-647)
MCITP-VA (70-669, 70-693, 70-647)
MCITP-EMA 2010 (70-662, 70-663)
MCITP-DBA 2008 (70-432, 70-450)
MCTS: ISA Server 2006 (70-351) - seems to have been retired, is 70-557 the replacement?
Whereas these interest me but do not directly relate to my current job (but would still be useful!) -
CCNA (Plus Voice/Security)
CCNP (after the above)
CCDA
Linux+
You see my problem with lack of focus?
