From departure go to Farnboro LARS on 125.25 once clear of Kenley gliding site. They will be able to see you from the Epsom Racecourse area. Needn't bother Thames on 132.7 or SVFR 119.9.
They can help co-ordinate through the Odiham MATZ - though there may be gliding at weekends so plan to avoid their ATZ.
Rest as said - should be quite uneventful - just don't make it hard on yourself - avoid the DA's unless you want the Faff practice!
The only thing re' the Yeovilton AIAA is keep a VERY good lookout! Otherwise it shouldn't be too tricky if you are used to flying around "tin-can-alley"! (The airspace between LF-KB around OCK up to 2.4A!!) ...only the aircraft might be a tad faster!!!!
Have fun - and if you ever need any ballast...............!
